Knife Gate Valve

Soft Seat Knife Gate Valve

This is designed according to the MSS SP-61,81(Class 150LB) and MSS SP-135 (Class 150LB, 300LB).
General knife gate valves are designed to be suitable for the control of fluids of large particles such as dregs, sediments, etc. In addition, this is of a metal seat type, so there are an allowed criterion for water leakage and a direction, and thus the installation direction shall be considered when installing a valve. The soft seat type has no allowed criterion of water leakage and is designed to be easily installed in both directions. In addition, this can be used in a pure liquid state of fluid line as well to replace other kinds of valves already installed, and was developed to avoid seat leakage even under a pressure of soft seat knife gate v/v 150LB, 300LB in particular.

Metal Seat Knife Gate Valve

This is designed according to the MSS SP-61,81(Class 150LB) and MSS SP-135(Class 150LB, 300LB)
General knife gate valves are designed to be suitable for the control of fluids of large particles such as dregs, sediments, etc.
In addition, this is of a metal seat type, so there are an allowed criterion for water leakage and a direction, and thus the installation direction shall be considered when installing a valve. Metal seat knife gate valve of KCL manufactured according to the MSS standard, shall not exceed the maximum leakage allowance of 40ml/min/NPS(1.6ml/min/DN) for the pressure of 40psi(2.8bar).
