Function
FunctionThe Rubber Seat Gate Valve is designed to provide reliable, full shutoff in a variety of systems, such as water pipelines, HVAC systems, and fire protection systems. The resilient rubber seat provides an airtight seal, ensuring that no fluid escapes when the valve is closed. When the valve is opened, the rubber seat allows full-flow passage without creating significant turbulence or friction, thus minimizing pressure drop.
The non-rising stem (NRS) design allows for more efficient use of space, as the stem does not extend outside the valve body during operation. This design makes it suitable for areas with limited vertical clearance, such as underground installations. Easy to operate with a manual handwheel or electric actuator, the valve is also designed for low-maintenance operation with quick replacement of the seat and stem components when needed.
The valve features a resilient rubber seat that ensures a leak-tight shutoff, even in fluctuating pressure conditions. With full bore design, it provides minimum resistance to flow and reduces the risk of sediment buildup. It is available in a wide range of sizes, from DN50 to DN1200, with either flanged or grooved connections. Easy to operate, the valve can be fitted with either a manual handwheel or an electric actuator, depending on the application needs.
