There are two types of actuators: membrane type and piston type; There are two types of functions: post valve pressure regulation for pressure relief (B-type) and pre valve pressure regulation for pressure relief (K-type). The nominal pressure ratings of products include PN16, 40, and 64; Valve body diameter range DN20~300; There are three levels of leakage: Level II, Level IV, and Level VI; The flow characteristic is fast opening; The pressure is adjusted in stages from 15 to 2500kPa. It can be combined as needed to meet the user's working conditions.

Product features:
The self operated pressure regulating valve does 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 intersects 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 detection accuracy and sensitive action of the actuator.
Adopting a pressure balancing mechanism, the regulating valve responds sensitively and controls accurately.

Summary: The direct acting self operated pressure (differential pressure) regulating valve (V230 self operated pressure regulating valve) is composed of valve body,valve seat,valve core and other parts.It is an energy-saving product that can automatically adjust the pressure only by the pressure change of the regulated medium without external energy.It can be used for pressure control of non corrosive (maximum temperature 350 ℃) liquid,gas,steam and other media It is widely used in petroleum,chemical industry,metallurgy,light industry and other industrial sectors as well as urban heating and heating system.
Introduction: ZFQ-1 explosion-proof fire-proof breathing valve produced by our company is a relatively new product in China. It is a new product with flame arrester and breathing valve. Its new structure is the first in China. It is a necessary safety equipment for petrochemical storage tank. Its biggest advantages are good fire resistance, stable suction performance, simple structure, light weight and convenient maintenance. The product is suitable for storage of class a oil with flash point lower than 28 ℃ and class B oil with flash point lower than 60 ℃, such as gasoline, kerosene, diesel oil, crude oil, toluene, ethanol, aromatics, sulfur and other media tanks. It works normally in the temperature environment of -35 ℃ -60 ℃.
ZMBQ pneumatic film cutting valve adopts top guide structure, with multi spring actuator.It has the advantages of compact structure, light weight, sensitive action, S-streamline fluid channel, small pressure drop loss, large valve capacity, convenient disassembly and assembly, etc.
Overview of ZX pneumatic diaphragm three way control valve: ZX new series pneumatic diaphragm three-way control valve adopts cylindrical thin-wall window valve core guide,which is different from the bushing guide of plunger valve core.Equipped with multi spring actuator.ZX type pneumatic diaphragm control valve has the advantages of simple structure,light weight,small volume and convenient disassembly.Widely used in accurate control of gas,liquid and other media,process parameters such as pressure,flow,temperature,liquid level to maintain a given value.The utility model is suitable for the occasions where one fluid flows out in two paths through the three-way valve or two fluids are combined into one fluid through the three-way valve. This series of products have two kinds of three-way confluence (ZXQ) and three-way shunt (ZXX). The nominal pressure rating is 1.6, 4.0 and 6.4Mpa, and the diameter range of valve body is DN25-200. The applicable fluid temperature ranges from - 60℃ to + 450℃.The leakage standard is grade IV.There are two kinds of flow characteristics:straight line and parabola.
ZAZXE electric three-way regulating valve (sub) flow control valve using cylindrical thin-walled window spool guide.
Small flow control valve is a special control valve for the control of small flow, can control the flow of all kinds of gas, liquid, steam, KV value up to 0.005.Therefore, it can be used in many occasions where accurate control of small flow rate is needed, such as laboratory test equipment, or industrial equipment in mass production, to control the small flow rate of chemicals, dyes, flavors and other additives.
HAA ordinary Angle valve is a top guide structure of the regulating valve.The valve body structure is close together, the pressure drop loss is small, the flow is large, the adjustable range is wide, the flow characteristic accuracy is high, the dynamic stability is good, the valve core guides the area to be large, the vibration resistance is good.
Eccentric rotary valve is also called CAM deflection valve.
Product introduction: ZZY type self operated pressure regulating valve does not need additional energy. It uses the self energy of the regulated medium and the power source to introduce the actuator to control the position of the valve core, and changes the pressure difference and flow at both ends to stabilize the pressure in front of (or behind) the valve. It has the advantages of sensitive action, good sealing, low power of pressure set point wave and so on. It is widely used in the automatic control of pressure reduction and pressure stabilization of gas, liquid and steam medium.
