10ZXM pneumatic sleeve control valve
It is widely used to accurately control the process parameters of gas, fluid, steam and other media, such as pressure, flow, temperature, liquid level to keep at the given value. It is especially suitable for the occasions with large allowable flow, large pressure difference and low leakage requirement.
This series of products have many varieties, such as adjusting type, adjusting cut-off type, bellows sealing type, jacket insulation type, etc. The nominal pressure rating of the products are PN10, 16, 40 and 64; The diameter range of valve body is DN20 ~ 200. It is suitable for fluid temperature from - 200 ℃ to + 560 ℃. There are IV or VI leakage standards. The flow characteristics are linear or equal percentage. A variety of varieties and specifications are available.
Product features:
1.Adopt balanced valve core structure, small axial balance force, allowable pressure difference and good stability.
2.Strong interchangeability of sleeve, easy disassembly and repair.
3.The all metal valve core structure is suitable for various working situations, reaching the IV level leakage standard, ZXMO type soft seal structure valve core reaching the VI level leakage standard, ZXMP type soft seal structure valve core reaching the VI level leakage standard.
4.The valve body is designed as a constant cross-section low flow channel according to the principle of fluid mechanics, with a large adjustable range, an inherent adjustable ratio of 50, and a 30% increase in the rated flow coefficient.
5.The actuator adopts multi spring structure, which reduces the height by 30% and weight by 30%.
6.ZXPV bellows seal type control valve forms a complete seal to the moving valve stem, blocking fluid leakage.
7.ZXPJ type control valve is equipped with heat preservation jacket, which is used in the occasions where the fluid is easy to crystallize and solidify after cooling.

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.
