铸铁明杆软密封闸阀

描述

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:

产品主要特点：

1. OS&Y明杆： 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. 操作扭矩小： Lightweight wedge and brass yoke nut make manual operation easy.
5. Coated Body: Epoxy powder coating provides long-term corrosion resistance.

应用：

适用于 供水与配水, 泵站, 消防系统以及 Industrial Cooling Water. Specifically suited for above-ground installations where the open/closed position must be visible.
