The HAT thermostatic valves control fluid temperature in dozens of applications to keep systems warm and prevent freeze damage. The thermal actuator inside the valve continuously senses the temperature in the line and will modulate open to initiate flow if the temperature falls below the valve's set-point. Then when the temperature rises back above the set-point, the HAT valve modulates closed to maintain constant discharge temperatures and minimize waste.

TV/HAT temperature control valves operate the same as HAT valves, but are used in conjunction with tubing and tracing systems using pre-traced tubing bundles. These versatile valves are ideal for replacing conventional steam traps on winterization tracing, instrument tracing, condensate return system freeze protection, process tracing and other applications requiring in-line flow control based on temperature.

HST thermal shutoff valves protect electronics in sample analyzers from over-temperature in the event of a sample cooler failure. Installed after the sample cooler in a sampling system, the HST continuously senses the media temperature and will automatically close if the desired sample temperature is exceeded to prevent damage to expensive sensors and analyzers. Once the temperature cools to 10ºF below the valve's set-point, the HST will open and resume flow.

HAT/RA thermostatic valves are used to regulate the flow of cooling water, glycol or other cooling media in applications requiring economical removal of heat from equipment or a process. The valve modulates between open and closed to maintain a constant fluid temperature in a system even as operating conditions vary.

HAT/RA-LP valves are designed to intentionally leak when closed at a set rate to efficiently monitor process temperature and minimize air bleed off. The thermal actuator is constantly sensing the fluid temperature via the leak port and modulating the valve between open and closed to maintain a constant fluid temperature. Typical leak port rates range from 1/8 to 1 GPM at 60 PSIG.

TV/HAT-RA valves operate the same as HAT/RA valves, but they are installed in systems via tube compression fittings rather than pipe thread connections to regulate coolant flow to maintain a constant fluid temperature.

These valves operate the same as HAT/RA-LP valves, but they are installed in applications where tubing rather than piping is used to continuously monitor the changing equipment temperature via a controlled leakage.

TV/SC-I valves maintain the temperature in instrument enclosures to protect instrumentation from freezing or overheating from an uncontrolled heating element. The TV/SC-I valve is installed into the wall of the enclosure with the thermal element inside the enclosure to sense the ambient temperature and regulate the steam supply to accurately maintain the desired temperature in the enclosure.

TV/SC-IR valves are installed in instrument enclosures for cooling instead of heating. These valves open on rising temperatures to regulate the flow of glycol, water and other cooling media to keep the instrument enclosure from over-heating.

TV/SC-A valves can be used in hundreds of freeze protection applications to control the flow of steam, gas, or fluid based on ambient temperatures. The TV/SC-A senses the air temperature and will open to initiate flow when the temperature drops below the valve’s set-point. It then automatically turns off the heating media when air temperatures rise back above the valve’s set point, saving thousands of dollars in operating cost.

ITCH assemblies are ThermOmegaTech®’s complete solution for instrument enclosure heating control. This assembly maintains the optimal temperature in an enclosure, protecting the instrumentation from freezing and providing steam control to avoid overheating. It comes complete with a steam coil, mounting brackets, TV/SC/A, two TV/HAT valves and tubing bulk-head fittings.

The US/S-X valves regulate the flow of heating media in closed loop systems in response to the process temperature or the pipe’s surface temperature. Either installed with the sensing end immersed in the process fluid or mounted non-invasively via a hose clamp on the outside of the pipeline, these valves sense the fluid temperature to control heat trace lines.

US/S-XR valves control cooling media to economically remove heat from equipment or a process. These valves sense the process temperature and will open on rising temperatures to allow cooling fluid in to keep a process from overheating.

The TV/US-X valves operate the same as the US/S-X valves where the sensing end is immersed in the process fluid to prevent overheating, but the heating media is connected with tube compression fittings instead of pipe fitting.

TV/US-XR valves operate the same as the US/S-XR valves where the sensing end is immersed in the process fluid but the cooling media is connected via tube compression fittings rather than pipe thread connections.
