Details Description
Groove Rising Stem Fire Gate Valve
* Groove rising stem fire gate valve is a type of gate valve specifically designed for use in fire protection systems. It is characterized by the presence of a groove on the stem of the valve, which allows for visual indication of whether the valve is open or closed.
* For a rising stem valve, the stem will go up while opening the valve and move down when you close the valve. You can see in the image. In inside screw design, the threaded portion of the stem is in contact with the flow medium and when you open the valve, handwheel rise with the stem. Whereas in the case of outside screw design, the only smooth portion is exposed to the flow medium and stem will rise above the handwheel. This type of valve is also known as OS & Y valve. OS & Y means outside steam and York.
Products Features

- Non-toxic powder epoxy resin spraying on botn inside and outside of the valve to enhance corrosion resistance and improve water quality.
- The valve plate is covered with rubber both inside and outside to guaranteed good sealing. It has strong connection to avoid fall off after long-term use.
- Thrust bearings reduce frictional resistance and reduce operating torque.
