V230 self operated pressure regulating 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.

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.

Product introduction: Z941 electric heat transfer oil special gate valve is widely used in petrochemical, thermal power plants and other oil and steam pipelines as opening and closing devices to connect or cut off the medium in the pipeline.

Product Overview Electric flange ball valves are mainly used to cut off or connect medium in pipelines, and can also be used for fluid regulation and control. Compared with other valve types, they have the following advantages. 1. Low fluid resistance. Ball valves have the smallest fluid resistance among all valve types, and even for reduced diameter ball valves, their fluid resistance is relatively small. 2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem balance and flexible for long-term operation. 3. The valve seat has good sealing performance, using sealing rings made of materials such as polytetrafluoroethylene, which are easy to seal in structure. Moreover, the sealing capacity of the ball valve increases with the increase of medium pressure. 4. The valve stem seal is reliable. As the valve stem only rotates without lifting, the packing seal of the valve stem is not easily damaged, and the sealing capacity increases with the increase of medium pressure. 5. Due to the good self-lubrication of materials such as polytetrafluoroethylene, the friction loss with the ball is small, and the service life of the ball valve is long. 6. The bottom mounted valve stem and the convex step of the valve stem head prevent the valve stem from spraying out. If a fire causes damage to the valve stem seal, metal contact can also be formed between the convex step and the valve body to ensure the valve stem seal. Electric ball valve is a rotating valve with a 90 ° angle, with excellent sealing performance, large flow coefficient, small flow resistance coefficient, simple structure, long service life, and easy maintenance. Equipped with electric cylinder type actuator. The product is widely used in system control in the chemical, petroleum, light textile, electric power, food and pharmaceutical, refrigeration, and paper industries.

Valve Usage The Q46, Q16, and Q66 series four way ball valves are called bidirectional water supply switching valves (also known as air reversing switching valves in petrochemical systems) in power plant systems, and are suitable for circulation systems of liquid, gas, dust, slurry, and solid particle media. Replacing the working principle of the process manifold and valve group with a four way ball valve simplifies the program, facilitates operation, reduces costs, facilitates control, and has good synchronization. Basic model Common four way ball valve models include: q16f, q46f, q46h, q46y, q346f, q346n, q946f, q66f, etc.
