Features
Leflow provides high performance gate valve products, including Wedge gate
valve, Pressure seal gate valve, Knife gate valve, Flat gate valve and Bellow
seal gate valve. The OS&Y stem is most popular, but Non-Rising Stem type is
also in our scope. Both flexible and Solid disc are available. For big size or
Big pressure valve, By-pass design is optional.Below seal gate valve also falls
in our ability.
A gate valve, known as a sluice valve, is a valve that opens by lifting a
barrier (gate) out of the path of the fluid. When fully open, the typical gate
valve has no obstruction in the flow path, resulting in very low flow
resistance. The size of the open flow path generally varies in a nonlinear
manner as the gate is moved. This means that the flow rate does not change
evenly with stem travel.
CAST STEEL GATE VALVE-DIN is usually for working condition in which the valve
is not opened or closed frequently, and supports gate fully open or fully
closed. It’s not suitable for adjustment or throttling.
Gate valve includes three types-Wedge gate, Knife Gate and Parallel Gate.
The disc of Wedge gate valve comes with Solid Type and Flexible Type.
Flexible Wedge Gate Valves design consists of two independent and
flexible wedge halves, that allow a relative movement to accommodate changes
in the body seat angles.
Solid wedge is designed in one-piece model while flexible wedge offers
a wedge shape for both seats.
