Gas pressure reducing valve YK43X/H

The self operated pressure regulating valve series products have three structures: single seat (ZZYP), sleeve (ZZYM), double (ZZYN), and so on; There are two types of actuators: membrane type and piston type; There are two types of functions: pressure regulation after the valve for pressure reduction (Type B) and pressure regulation before the valve for pressure relief Section (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. The self operated pressure regulating valve does not require external energy, and uses the energy of the regulated medium as the power source to introduce the 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. Self operated pressure regulating valves have the advantages of sensitive action, good sealing performance, and low pressure set point ripple force. Self operated pressure regulating valves are widely used for automatic control of gas, liquid, and medium pressure stabilization or pressure relief stabilization.

Product Overview The V230 series self operated pressure regulating valve is an energy-saving control valve that relies on the pressure of the medium itself and does not require external energy for self control. It is used as a pressure control device for gases, liquids, and steam temperatures (≤ 350C) and other media. Product Features Maintenance-free, self pressure control of the medium, no need for external energy, significant energy-saving effect, stainless steel corrugated pipe pressure balance type, low imbalance force, high sensitivity, support for internal and external pressure setting points with a wide range, and can be easily adjusted by adjusting the nut. The actuator and spring can be assembled at will, thus achieving multiple adjustment ranges for high sealing requirements. The use of soft sealing valve core standard low noise valve core for higher noise reduction requirements, Special models with noise cancellers can be used with standard modular design, high level of standardization, and multiple combination controls can be achieved through combination components

This series of proportional pressure reducing valves is a regulating valve that proportionally reduces the pressure of the medium flowing through it. It utilizes the pressure generated by the different cross-sectional areas of the piston at both ends inside the valve body to change the pressure behind the valve and achieve the purpose of reducing pressure. Stable operation, capable of reducing both dynamic pressure and static pressure, with precise pressure reduction ratio. The valve has a simple structure, high-quality material selection, low price, and reliable performance. The reference ratios include 2:1, 3:1, 4:1, 3:2, 5:2, etc.

This series of pressure reducing valves belongs to the pilot piston pressure reducing valve. It consists of two parts: the main valve and the pilot valve. The main valve is mainly composed of valve seat, disc, piston, cylinder liner, and spring parts. The pilot valve mainly consists of valve seat, valve disc diaphragm, spring, adjustment spring, and other components. This product has made significant improvements on the basis of ordinary pressure reducing valves, increasing the piston area, changing the throttling structure, changing the sealing form, increasing the flow area, etc., thereby greatly improving performance in improving steam pipeline, flow rate, service life, and other aspects. This product is mainly used in steam pipelines, suitable for steam pipelines with large changes in flow rate and inlet pressure.

The 200X pressure reducing valve mainly controls the outlet pressure of the main valve by adjusting the pressure reducing pilot valve. The outlet pressure of the main valve does not change due to changes in inlet pressure and flow rate. The outlet pressure is safely and reliably maintained at the set value of the pilot valve, and the set value can be adjusted to achieve the purpose of reducing pressure in the pipeline. This valve has precise pressure reduction, stable performance, convenient adjustment, and long service life. Suitable for domestic water supply, fire water supply, and other industrial water supply network systems.

ZGPV multifunctional pressure reducing valve can be used for media such as water, steam, natural gas, oxygen, nitrogen, hydrogen, etc. ZGPV pressure reducing valve is an energy-saving control device that does not require external driving energy, relies on the pressure of the regulated medium itself as the power source and its medium pressure changes, and automatically adjusts according to the predetermined set value. It integrates detection, control, and execution functions into one valve, forming an independent instrument control system. ZGPV pressure reducing valve is particularly suitable for urban heating, heating, and situations where there is no external power supply or gas supply, and steam pressure control is required due to its advantages of no external energy source, simple structure, convenient use, and low maintenance workload. According to foreign reports, the use of this product in urban heating and heating systems has significantly improved energy efficiency by 30% -40% compared to before.

The outlet pressure of the pressure reducing valve can be set according to user needs and kept basically constant; The pressure behind the valve does not change due to changes in inlet pressure, nor does it change due to changes in outlet flow rate. Suitable for various situations where dynamic and static pressure reduction is required in domestic water supply, production water supply, fire water supply, HVAC water supply systems.

Multi-function universal connection elbow, this product is suitable for seamless pipe, welded pipe, ductile pipe, cast iron pipe (PVC, PPR, PE pipe, steel plastic pipe), the emergency repair with water pressure operation, no electricity, only a wrench quick connection repair, the pipe has telescopic anti-detrench effect, reduce telescopic device, excavation area is very small.
