An internal pressure balancing mechanism is composed of 316 bellows +304 balance springs
The connecting nut will disassemble the adjusting mechanism and the actuator.
The thermostat is a temperature regulating valve actuator, which according to the liquid can not be compressed and thermal expansion and contraction of the pressure of work, there are two types of thermostat temperature control range of choice, special type: no lubrication of high cleanliness of the working environment.
1. Simple installation. 2. No power source. 3., Adjust the settings simple. 4. Balance spool design. Self heating valve without external energy saving control valve, for non corrosive gas and steam medium temperature control of various heaters. Using bellows + spring to do pressure balance, no parts, high sensitivity, low noise, reliable performance.
Self operated temperature control valve does not need external energy for automatic temperature regulation. It is suitable for steam, hot water, hot oil as the medium of various heat transfer conditions. Widely used in heating, air-conditioning, hot water in the automatic temperature regulation, as well as special conditions of automatic temperature regulation, such as chemical, textile, pharmaceutical and other production projects.
