Fire pressure reducing valve

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.

Flange check valve is to rely on the flow of the medium itself and automatically open, close disc, used to prevent the medium backflow valve, also known as the check valve, one-way valve, reverse flow valve, and back pressure valve.

ISG/IHG vertical pipeline centrifugal pump，It is a combination of excellent hydraulic models selected by domestic water pump experts, using the performance parameters of IS centrifugal pumps, and cleverly designed on the basis of ordinary vertical pumps. At the same time, suitable hot water, high temperature, and corrosive chemical pumps and oil pumps are dispatched on the basis of ISG type according to different usage temperatures, media, etc. It has the advantages of high efficiency, energy conservation, low noise, and reliable performance.

This series of diaphragm valves can be applied to different fluid medium pipelines at different temperatures based on different coating materials, serving as an opening and closing mechanism to control medium flow.
