Plunger valves are linear-motion shut-off valves that use a metal plunger and seal ring to achieve zero-leakage on-off control, suitable for high temperature and pressure media. We supply manual and actuated plunger valves sourced from qualified factories, with cast steel and stainless steel construction, metal-to-metal or PTFE sealing options. Widely used in steam, water and oil pipeline systems. Featuring durable sealing and long service life, ideal for frequent operation industrial applications.
