Product Details
WZ501
Commander-operated self-operated pressure regulating valve
Self-operatde Regulatiug Valve
Product overview
WZ501 type commander-operated self-operated pressure regulating valve is an energy-saving pressure regulating valve that does not require external energy but only relies on the pressure change of the adjusted medium itself to achieve automatic adjustment and stabilize the pressure after the valve is constant.
The valve pressure setting is realized on the commander, so it is convenient, fast, time-saving and labor-saving. It can be continuously set in the operating state: the control accuracy is high, which is twice as high as that of the general ZZY type direct operation self-operated pressure regulating valve, and is suitable for occasions with high control accuracy requirements. The detection and execution components are made of high temperature resistant materials and can be used in water vapor occasions at temperature (200 ℃) without condenser.
