Instructions for use:<\/strong>
\nZZYP type self-operated pressure regulating valve (steam pressure reducing valve) does not need to add energy, and uses the energy of the adjusted medium as the power source to introduce the actuator to control the position of the valve core, change the pressure difference and flow rate at both ends, and make the pressure in front of the valve (or behind the valve) stable. It has the advantages of sensitive action, good sealing, and small fluctuation force at the pressure set point, and is widely used in the automatic control of gas, liquid and steam medium pressure reduction and pressure regulation or pressure relief and regulation.
\nZZYP self-operated pressure regulating valve series products have single seat (ZZYP), sleeve (ZZYM), double (ZZYN), three structures; There are two types of actuators: membrane type and piston type; There are two types of pressure adjustment: pressure adjustment after the valve for pressure reduction (type B) and pressure adjustment for pressure relief (type K). The nominal pressure level of the product is PN16, 40, 64; the valve body diameter range DN20~300; There are three levels of leakage volume: level II, class IV and class VI; The flow characteristics are quick opening; The pressure is segmented from 15~2500Kpa. It can be combined to meet the requirements of user working conditions as needed.<\/p>\n

Product features:<\/strong>
\nSelf-operated pressure regulating valves (steam pressure reducing valves) do not require additional energy and can work in places without electricity or gas, which is convenient and energy-saving.
\nThe pressure segment range is fine and intersecting, and the adjustment accuracy is high.
\nThe pressure setpoint can be set continuously during operation.
\nFor the pressure adjustment after the valve, the ratio of the pressure in front of the valve to the pressure behind the valve can be 10:1~10:8.
\nRubber diaphragm detection, actuator measurement accuracy is high and action is sensitive.
\nThe pressure balance mechanism is used to make the control valve responsive and precise control.<\/p>\n
