Thermostatic Valves

Thermostatic Valves are a simple and reliable control solution requiring neither electricity nor control air. An example of application is automatic control of water temperature in cooling systems. The valves are available with remote or built-in sensor.

AVTA thermostatic valves are widely used for temperature control in many different sorts of equipment and installations where cooling is required.

WVTS, Thermostatic valves with temperature sensitive sensor Cooling water valves of type WVTS are suitable for controlling the temperature of a flow of water or neutral brine. WVTS opens on rising sensor temperature.</FONT>

  • Large self-acting cooling water valves for accurate flow control based on sensor temperature 
  • Open on rising temperature 
  • Cast iron valve body 
  • Thermostatic pilot elements (2 or 5 m capillary tube) ordered seperately

BVTS, Thermostatic bio-mass valve

The BVTS valve is designed for protection of bio-mass boilers, stoves and solar systems. The valve has two functions:Overheat protection: If the water temperature exceeds 95° C the valve opens and hot water is discharged from the boiler or the built-in heat exchanger.Protection against backburning: If the temperature in the fuel feed system rises above 95° C the valve will dispense water to extinguish fire.

FJVA, Thermostatic valves without sensor

FJVA is a self-acting, thermostatic valve for use in cooling applications. The valve is commonly used in connection with hydraulic stations, and is often named the "fit and forget" valve, due to its immense reliability, proven throughout decades.

  • Self-acting cooling water valves for flow control based on temperature changes in the return line 
  • Bellows element acts as sensor 
  • Open on rising temperature 
  • Brass valve body 
  • By-pass in the valve ensures a constant minimum flow
