Flange steam 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.

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.

J41B Ammonia Globe Valve Product Overview: The structure of the valve body of the J41B ammonia stop valve includes straight-through, direct-flow and right-angle. Straight-through is the most common structure, but its fluid resistance is the greatest. Direct flow fluid has low resistance and is mostly used for fluids containing solid particles or high viscosity. Right-angle valve bodies are mostly forged, which is suitable for shut-off valves with smaller diameters and higher pressures. The middle flange is a square structure, and the valve stem is connected by an intermediate rod.

Electric stainless steel flange ball valve is a rotary type ball valve with an angle of 0~90 °. It has excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, convenient maintenance, long service life, equal valve channel and connecting pipe diameter, and the medium can flow almost without loss. Electric stainless steel flange ball valves are mainly divided into closed and adjustable types (with explosion-proof). Electric stainless steel flange ball valves can be divided into soft sealing valve seats and metal sealing valve seats based on their sealing performance. Soft sealing valve seats are suitable for temperatures ≤ 180 ° C, and metal hard sealing valve seats are suitable for temperatures ≤ 425 ° C. Electric ball valves are usually used in occasions with strict sealing requirements. In addition to controlling gas, liquid, and steam media, they are also suitable for controlling sewage and media containing fibrous impurities. They are widely used in fields such as petroleum, chemical industry, metallurgy, light industry, papermaking, power plants, refrigeration, etc.

Overview of pneumatic wafer ball valve: Pneumatic wafer ball valve is mainly used in short pipelines and special space occasions. It is mainly composed of single (double) acting pneumatic actuator and ultra-thin ball valve. It is a new generation of ultra-short flanged ball valve.

The exhaust valve is used for pipeline exhaust in independent heating systems, centralized heating systems, heating boilers, central air conditioning, floor heating, and solar heating systems. Because water usually contains a certain amount of air, and the solubility of air decreases with the increase of temperature, gas gradually separates from the water during the circulation process and gradually gathers together to form large bubbles or even gas columns. Due to the supplementation of water, gas is often generated.
