STC Adjustable thermostatic-type steam trap valves
STB Adjustable thermostatic-type steam trap valve
Structural principle
ST series trap valve is a new product of the heat static force type.The internal heat responsive element are filled with temperature-sensing mixture, which consist of temperature-sensing agent, saturated agent, stabilizers and bulking agent, making use of the expansion and contraction and the state transform to cause the valve automatically close or open, so as to achieve the purpose of drainage and steam-resistance. Choosing appropriate specifications is to fix the temperature range of the discharge of condensed water, within which range it can be adjusted by adjustable bolt according to the circumstance requirements.
