Operation
The TBV-PR integrates temperature control and pressure relief into one valve. The thermal actuator of the thermal bypass valve precisely adjusts the opening based on temperature fluctuations to control flow and ensure optimal system performance. Cooler fluid goes through the valve bypass, while hotter fluid goes through the system’s heat exchanger/cooler.
The built-in pressure relief function safeguards the system from excessive pressure buildup. When the pressure exceeds a predetermined threshold, the valve opens, allowing fluid to escape and reducing pressure to a safe level. Refer to the Bypass Mode with H/X path blocked graphic below.
This versatile valve can be incorporated into a 4-way manifold to efficiently direct fluid flow based on temperature, ensuring optimal system performance and safety.

Operation
ThermOmegaTech’s STVM® washdown station incorporates unique Venturi mixing technology to deliver water at the required temperature quickly, quietly, and on demand. Cold water enters the upper chamber of the mixing valve, while incoming steam enters the lower chamber. Mixing occurs as the two vortices collide, thoroughly mixing and heating the water through a Venturi diffuser with minimal noise and vibration.
Conventional washdown mixing stations that rely on multiple moving parts and use old spool and diaphragm technology are prone to premature failure due to mineral deposits and scaling. The necessary regular maintenance of these units to keep them running safely is very time-consuming and costly. The rugged STVM® mixer is unique because it has only one moving part, a thermal actuator within the mixing valve cartridge.
The patented mixing design ensures extended, uninterrupted use even if the water contains high mineral content. As the opposing vortices of steam and water enter the mixing valve, a scouring action occurs that minimizes the buildup of minerals and scale.
The Safe, Efficient Steam Water Mixing Station
An additional benefit of this design is what you don’t hear: the banging, popping, and crackling noises associated with cavitation that are prevalent in ordinary mixing stations. This smooth, quiet operation increases safety and reduces stress on the operator.
Safety is our priority, so every STVM® Washdown Station has two built-in safety features – interlocking ball valves to prevent steam-only operation and an automatic shut-off when output is 15°F over the unit’s temperature set-point (either 150°F or 185°F) or when cold water flow is interrupted.

Steam Water Mixing Valve Cartridge Operation
A steam and water mixing valve creates hot water when cold water enters the valve and moves from the inside out, while incoming steam moves from the outside in. Mixing occurs as the two flows collide, thoroughly combining and heating the water to the desired temperature.
Because of the unique mixing characteristics inside the STVM® steam mixing valve, it is capable of mixing steam and water without the usual noise and vibration associated with other types of mixers, eliminating operator stress, and making it ideal for workplace environments.
The unique flow characteristics of the vortices inside the valve create a scouring action that minimizes the effects of mineral deposits on the valve, assuring increased service life even under adverse conditions. As a safety feature, the thermal actuator in the valve outlet is designed to turn off the steam flow into the valve if the cold water flow into the valve is interrupted.
The STVM® cartridge for our STVM® industrial steam water mixing valves can be replaced in an installed station in minutes by simply unscrewing the cartridge with a standard wrench and inserting the new one. The used cartridge can then be cleaned by emerging it in a descaling solution, inspected, and reused.
This allows easy cleaning and service without removing the station from its installed location in food processing and other industrial facilities. The impact of production downtime can severely affect your bottom line. To maximize your uptime, be sure to have a spare STVM® cartridge assembly readily available to keep your operation running smoothly.

Operation
The EcoFlow® mechanical seal support system contains a highly reliable and repeatable thermal actuator that continuously senses the seal water temperature. If the seal water should exceed the specified factory set-point, the valve will modulate open discharging the hot water, displacing it with cool water. This cooler water will cause the EcoFlow® to modulate closed. This cycle will continue to occur as long as excessive heat is transferred to the seal water causing the water temperature to exceed the valve’s factory set-point.
Typical Applications
The EcoFlow® valve is installed on the seal water outlet of a mechanical seal to maintain a constant seal water outlet temperature. This increases seal life by ensuring an optimum seal environment while drastically reducing water consumption and significantly increasing cost savings.

- Optional side port feature allows flushing debris from inside valve
Benefits
- Self-operating – no external power source required
- Drastically decreases seal water consumption
- Increases water treatment efficiency
- Eliminates dry runs due to operator error
- Increases seal life
- Expands mechanical seal use to more applications
- Decreases operating cost
- Quick and easy installation
Seal Water Savings Example
To illustrate the water savings from the case study below that can be realized with EcoFlow®’s mechanical seal support system, we’ve used a typical seal manufacturer’s recommendation of 2.6 GPM to be used to flush the seals versus EcoFlow’s 0.05 GPM, operating 8 hours a day, 5 days a week (2080 hours per year).
Recommended: 2080 hours x 2.6 gallons per minute x 60 minutes = 324,480 gallons of water per year.
W/ EcoFlow: 2080 hours x 0.05 gallons per minute x 60 minutes = 6,240 gallons of water per year.
In our calculation, EcoFlow® can save ~318,000 gallons of water per year.

Operation of Passenger Rail Car Freeze Protection Valves
The ¾” thermostatic GURU PC® valve is installed at the lowest point within the potable water-bearing system of a passenger rail car. Its primary function is to prevent water from freezing when the car’s heating system is turned off.
This self-operating freeze protection valve continuously monitors ambient temperatures. It will automatically drain the water tanks of the rail car if the external temperature drops to the valve’s set-point of 35°F (1.7°C). This preemptive action protects the system from freezing and prevents potentially costly damage.
When power and heat are restored to the rail car, the valve warms up and closes, enabling the water tanks to be refilled before the car returns to service. As the valve operates mechanically, it requires no electrical or air connections.
To expedite the refilling process after a valve activation, we recommend using our electric heater assembly. The heater attaches to the valve’s thermal actuator and quickly warms it once power is restored, allowing the valve to close promptly and the system to be refilled efficiently.
To avoid unnecessary activations and nuisance dumping, we suggest replacing the cartridge assembly every two years, particularly if tests reveal sluggish or marginal closing performance. We offer a replacement cartridge kit to facilitate easy replacement without removing the Tee Body.
The GURU PC® valve is NSF/ANSI/CAN 61 & 372 Certified for use in potable water systems and has been rigorously tested to withstand shock and vibration, ensuring durability in harsh conditions. Compact, reliable, and in-line serviceable for ease of maintenance, the GURU PC® valve is the ideal solution to protect the potable water systems in passenger rail cars, including toilet modules and galleys, from freeze damage.

Operation
The 1″ thermostatic GURU PC® freeze protection valve is installed at the lowest point within the potable water-bearing systems on a passenger rail car to prevent the water from freezing when the car heat is turned off for switching locomotives or even brief layovers.
This self-contained freeze protection drain valve monitors ambient temperatures and will automatically drain the system if the air temperature falls to the valve’s set-point, 35°F (1.7°C), preventing burst piping and thousands of dollars in damage. Once the car heat is restored, the valve will modulate closed, allowing for the tank to be refilled before returning to service. Since the valve is completely mechanical, no electrical or air connections are required for the valve to operate.
To avoid a delay in refilling the water system and getting the passenger car back into service after a valve activation we recommend using our electric heater assembly. The heater attaches to the thermal actuator on the valve and will warm it up quickly once power is restored to the car. This allows the GURU PC® freeze protection valve to close and the potable water system to be refilled quicker after a drain occurrence.
NSF 61 Certified and shock and vibration tested, the GURU PC® is compact, reliable, and in-line serviceable for ease of maintenance.
