FAQ Section
What maintenance does a plunger valve require?
Plunger valves require minimal maintenance due to their robust design. Regular inspection of seals and lubrication of moving parts is recommended every 6-12 months depending on usage. The valve stem packing may need occasional adjustment to prevent leaks. In normal service conditions, our plunger valves can operate for years without major maintenance.
How does a plunger valve compare to other valve types?
Plunger valves offer several advantages over traditional valve designs. They provide superior sealing performance with lower operating torque compared to gate valves. The linear motion of the plunger creates less turbulence than globe valves, resulting in lower pressure drops. Unlike ball valves, plunger valves maintain excellent flow control throughout their entire stroke range, making them ideal for throttling applications.
Can plunger valves handle abrasive media?
Yes, our plunger valves are specially designed to handle abrasive fluids. The hardened plunger surface and specialized seal materials resist wear from particulate matter in the fluid stream. For extremely abrasive applications, we offer tungsten carbide coated plungers and ceramic seats that significantly extend service life. The design minimizes contact between moving parts and the media, reducing wear even in challenging conditions.
