Note: This plunger valve cannot be used for drinking water.

The low cost flanged plunger valve has a DN50 (2") bore size and a nominal pressure of 1.6 MPa. RDDLZ plunger valves are perfect for fluid control applications that require precise performance and reliable operation.

Specification

• Model: RDDLZ-PV-DN50
• Nominal Pressure: 1.6MPa
• Material: Carbon Steel
• Connection Method: Flange connection
• Medium: Water, steam, oil
• Applicable Temperature: ≤425℃
• Weight: 24kg

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: How to maintain a plunger valve?

Maintaining a plunger valve involves regular cleaning and lubrication to ensure proper functioning. Here are some steps you can follow:

1. Disassemble the valve: First, disassemble the plunger valve by removing the cap, spring, and plunger. You may need to consult the manufacturer's instructions to ensure proper disassembly.
2. Clean the valve: Once the valve is disassembled, clean all the parts thoroughly with acleaning solution that is compatible with the valve material. You can use a mild soap solution, or a specially formulated valve cleaner.
3. Inspect the valve: Inspect the valve for any damage or wear, such as cracks or scratches. If any damage is found, the valve may need to be replaced.
4. Lubricate the valve: After cleaning, apply a thin layer of lubricant to the plunger and other moving parts. Make sure to use a lubricant that is compatible with the valve material.
5. Reassemble the valve: Once the valve is clean and lubricated, reassemble it in the correct order. Ensure that all the parts are properly aligned and tightened.
6. Test the valve: Finally, test the valve to ensure that it is working properly. Check for leaks, proper flow, and ease of operation.

It is important to regularly maintain the plunger valve to prevent any issues and ensure a longer lifespan. The frequency of maintenance will depend on the valve's usage and the environment it operates in.
