Cast Steel Flanged Plunger Valve For High Temperature Medium Fluid Control

Cast Steel Flanged Plunger Valve For High Temperature Medium Fluid Control

Product introduction:

Plunger valve is a type of shut-off valve that utilizes the reciprocating motion of the plunger in the valve seat to achieve the opening and closing of the valve. Plunger valves mainly consist of valve bodies, valve covers, plungers, sealing rings, and springs. When the plunger moves towards the valve seat under the action of the spring, the contact pressure between the sealing ring on the valve seat and the plunger gradually increases until sufficient sealing pressure is reached before the valve is completely closed.

Plunger valve is one of the control valve products with a straight bottom opening. Its working principle is to directly use the contact seal between the plunger and the valve seat for flow control. Plunger valves are widely used in various industrial fields, such as chemical, petroleum, food, medicine, etc. Its main advantages are simple structure, reliable sealing, long service life, and a relatively large flow range. The plunger valve also has a special advantage of very accurate flow regulation and strong controllability. Therefore, plunger valves have been widely used in industrial automation control systems.

Plunger valves are more advantageous in conditions of high medium viscosity and low flow rate, and can achieve graduated flow regulation. Plunger valves have a simple structure and good sealing performance, so they are more commonly used in situations with corrosive media or high pressure

Product parameter:

Product features:

1. The direct contact sealing structure has good sealing performance and is suitable for some media that require corrosion resistance and wear resistance.
2. It has linear flow characteristics and accurate and reliable flow regulation.
3. Simple structure, lightweight and compact, easy installation and debugging, and long service life.
4. It can achieve bi-directional sealing, suitable for both positive and negative directions of the fluid.
5. Due to the direct contact and fine-tuning combination design between the plunger and valve seat, the control accuracy of the plunger valve is high, which can meet various precision requirements and is also relatively energy-saving and environmentally friendly.
