Cast Iron Rising Stem Soft-Sealed Gate Valve

Description

The Cast Iron Rising Stem Soft-Sealed Gate Valve is a flanged, resilient-seated isolation valve with an outside screw & yoke stem. As the handwheel turns, the stem rises with the wedge, giving clear visual indication of valve position. The rubber-encapsulated wedge seals against a smooth body bore for leak-free closure in clean and slightly contaminated water.

Main Parts and Materials:

Key Product Features:

1. OS&Y Rising Stem: Stem position indicates opening at a glance and keeps threads out of the medium.
2. Elastic Wedge Seal: EPDM vulcanized wedge ensures zero leakage and self-compensates for small deformations.
3. No Seat Pocket: Flat-bottom design prevents sediment build-up and keeps the seal reliable.
4. Low Operating Torque: Lightweight wedge and brass yoke nut make manual operation easy.
5. Coated Body: Epoxy powder coating provides long-term corrosion resistance.
