ZZY type flow control valve does not need external energy, use the energy of the medium to be adjusted as the power source to introduce the actuator to control the position of the spool, change the pressure difference and flow at both ends, and make the pressure before the valve (or after the valve) stable. It has the advantages of sensitive action, good sealing performance, small pressure setting point wave power, etc. It is widely used in the automatic control of gas, liquid and vapor medium decompression regulation or pressure relief voltage regulation.
There are two types of actuators in this series: diaphragm type and piston type; the type of operation includes post-pressure valve pressure adjustment (type B) and pressure relief valve front pressure adjustment (type K). The leakage level has three grades of grade II, grade IV and grade VI; the flow characteristics are quick opening; the pressure section is adjusted from 15 to 2500 Kpa. Can be combined as needed to meet user requirements.
The self-operated pressure regulating valve does not require external energy and can work in a place where there is no electricity and no gas, which is convenient and saves energy.
The pressure segmentation range is fine and crosses each other, and the adjustment accuracy is high.
The pressure setpoint can be set continuously during operation.
For post-valve pressure regulation, the ratio of pre-valve pressure to post-valve pressure can be 10:1 to 10:8.
The rubber diaphragm type detection, the actuator has high precision and sensitive action.
The pressure balance mechanism is adopted to make the control valve sensitive and precise.
