Product Details

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.

The customers shall discuss with Donghae Co., Ltd. to determine valve construction according to the fluid used and the installation environment.

A manufacturer of various type valve product for industry
We have produced knife gate valves since 2003, and have spared no investment and effort to develop the technology and to improve the quality according to the requirements of market. As a result, we developed the world's first knife gate valves for water service and the world's first soft seat slim gate valves which are applicable to the water, oil and gas lines with the appearance structure of knife gate valve. These products can substitute the gate valves which are applied to the whole industries, and the performance can satisfy the customers who want better one, which results the increase of demands. They can be used up to KS 10K and 20K of pressure level and ASME 150LB and 300LB. There is no seat leakage even at 40kgf/㎠ and no pileup of foreign substances at the lower part of vqlve bore, which enables to smoothly operate the valves. And they are the only valves for fluid block which are possible to control the flux and their fire safety structure enable to apply to important lines. DongHae has moving forward to customers' demands in the local and overseas markets by developing several valves for specialized uses as well as the knife gate valve for water service and the soft seat slim gate valve for industrial purposes. Our company will grow as your trustable Valve Partner by keeping our efforts like this.
