産業用プランジャーバルブ / ピストンバルブ - ハイシール, メンテナンスの少ない調整ソリューション

The industrial Plunger Valve (or Piston Valve) is an advanced flow regulating device engineered to eliminate the persistent stem packing leakage and seat erosion issues found in conventional globe valves. Its innovative design utilizes a precision-machined plunger and two long-lasting resilient sealing rings (typically PTFE) that compress to create a tight barrier. This provides exceptionally low external leakage and zero seat wear, making it the ideal, low-maintenance choice for controlling high-pressure steam, thermal oil, and process fluids.

顔立ち

An advanced regulating valve that uses a robust plunger and resilient sealing rings to achieve zero external leakage, minimize seat wear, and ensure low maintenance compared to traditional globe valves.

✅Superior Leakage Elimination: The design utilizes two flexible, compressed sealing rings (PTFE/Graphite) that create a vast sealing surface against the plunger. This highly effective system prevents external leakage past the stem, surpassing the performance of traditional gland packing.

✅Significantly Reduced Maintenance: By eliminating the frequent need for stem packing adjustment or replacement, and preventing seat erosion, the valve drastically lowers maintenance requirements, leading to reduced operational costs and increased system uptime.

✅Excellent Throttling & 規制: The proportional movement of the plunger provides precise control over fluid flow. This characteristic makes the valve highly effective for throttling and accurate regulation of steam, 湯, and other process media.

✅Wear-Free Seating Surfaces: Unlike traditional valves where the disc lands directly on the seat, the plunger design protects the seating surfaces from high-velocity erosion and wear, ensuring the valve maintains its tight seal and longevity.

✅丈夫な & Robust Construction: Typically built from cast steel or stainless steel (implied for high-pressure/temp), the plunger valve is constructed for high durability and is an ideal upgrade solution for replacing unreliable globe valves in critical temperature and pressure applications.
