Features

• When switching on and off the plunger valve, the plunger moves slowly in the sealing ring and the contact surface is hardly worn.
• The sealing ring adopts new non-toxic sealing material with strong elasticity and high wear resistance, which is reliable and durable.
• In the valve between the plunger and the sealing ring using interference fit, thus ensuring the sealing of the valve and eliminating internal and external leakage.
• When closed, the plunger is inserted into the lower sealing ring to cut off the flow channel.
• When opened, the plunger is detached from the lower seal ring but remains hidden in the upper seal ring, keeping it isolated from the outside world and preventing leakage.

Applications

Plunger valves are commonly used in a variety of industrial applications where reliable and precise control of fluid flow is required. Some typical applications include chemical processing, oil and gas production, power generation, and water treatment. 

Tips: What is the difference between a plunger valve and a piston valve?

• Plunger valves and piston valves are both types of valves used to control the flow of fluids or gases in various industrial and mechanical applications. However, they differ in their design and operation.
• A plunger valve consists of a cylindrical body with a plunger or piston that slides inside it to control the flow. The plunger is connected to an actuator, such as a lever or solenoid, which moves it back and forth to open and close the valve. The plunger creates a seal against the valve body to prevent leakage.
• In contrast, a piston valve has a piston that moves up and down inside the valve body to control the flow. The piston is connected to an actuator, such as a pneumatic or hydraulic cylinder, which moves it up and down. The piston creates a seal against the valve body to prevent leakage.
• The main difference between the two types of valves is the way they control the flow of fluid or gas. Plunger valves control the flow by sliding the plunger back and forth, while piston valves control the flow by moving the piston up and down. This difference in operation can affect the performance of the valve in certain applications.

Overall, the choice between a plunger valve and a piston valve depends on the specific application and the required performance characteristics, such as flow rate, pressure, and temperature range.
