Overview

ZZYP-16P DN300 stainless steel self operated pressure differential regulating valve is composed of valve body, valve seat, valve core, balance spring and other components. It is an energy-saving product that does not require external energy and uses the pressure changes of the regulated medium to automatically regulate. It is introduced into the actuator based on mechanical principles to generate force and push the valve core element up and down to achieve automatic regulation. The valve maintains constant pressure or pressure before or after the valve. The feature of this product is that it can work in places without electricity or gas, and the pressure setting value can be adjusted freely during operation. Adopting fast opening flow characteristics, it has sensitive action and good sealing performance, and is applied to

Product Details

ZZYP-16P DN300Stainless steel self operated pressure differential regulating valveIt is composed of valve body, valve seat, valve core, balance spring and other components. It is an energy-saving product that does not require external energy and uses the pressure changes of the regulated medium to automatically adjust. It is based on the principles of mechanics to introduce the controlled medium into the actuator to generate force and push the valve core element up and down to achieve automatic adjustment. It maintains constant pressure or pressure before or after the valve. The feature of this product is that it can work in places without electricity or gas, and the pressure setting value can be adjusted freely during operation. Adopting fast opening flow characteristics, with sensitive action and good sealing performance, it is applied to automatic control of gas, liquid, steam and other medium pressures in industrial equipment such as petroleum, chemical, power station, light industry, printing and dyeing.

Without the need for external energy, using the energy of the regulated medium itself as a power source, introducing an actuator to control the position of the valve core, changing the pressure difference and flow rate at both ends, and stabilizing the pressure before (or after) the valve. It has the advantages of sensitive action, good sealing, and small pressure fluctuations, and is widely used in automatic control of gas, liquid, and steam media for pressure reduction and stabilization or pressure relief and stabilization. This series of products has three structures: single seat (ZZYP), sleeve (ZZYM), and double seat (ZZYN); There are two types of actuators: membrane type and piston type; The types of action include pressure regulation after the pressure reducing valve (Type B) and pressure regulation before the pressure relief valve (Type K). The nominal pressure rating of the product includes PN16, 40, and 64; Valve body diameter range DN20~300; There are three levels of leakage levels: I * *, IV, and V * * *; The traffic characteristic is fast opening; The pressure is adjusted in stages from 15 to 2500 kPa. Can be combined as needed to meet user operating requirements.characteristicSelf operated pressure regulating valves do not require external energy and can work in places without electricity or gas, which is both convenient and energy-saving. The pressure segmentation range is fine and intersecting with each other, with high adjustment accuracy. The pressure setting value can be continuously set during operation. Adjust the pressure behind the valve, with a ratio of 10:1 to 10:8 between the pressure before and after the valve. Rubber diaphragm type detection, with high precision and sensitive action of the actuator detection. Adopting a pressure balancing mechanism to make the regulating valve responsive and accurate in control.
