Thermostatic valve WATTS STS 20

Thermostatic valve WATTS STS 20

APPLICATION:

• Heating systems.

DESCRIPTION:

• Designed to protect solid fuel boilers from overheating at a system power of not more than 93 kW.
• The function of the valve is independent of the pressure in the system.
• The valve is triggered to open when the temperature in the supply pipe reaches 95°C, thereby opening the water supply to the boiler cooling circuit. Thus, the water temperature in the boiler should not rise above 110°C.
• Two independent temperature sensors provide high reliability of the valve. Even if one of them fails, the valve will perform its function.
• All-metal execution possesses high resistance to external influences.
• If necessary, the valve piston can be easily replaced.
• The valve body is made of MS 58 nickel-plated brass.
• Both connections are 3/4" female thread.
• Immersion tube 142 mm, 1/2" male thread.
