Knife Gate Valve

UTMOST, as one of the most professional knife edge gate valve manufacturersin China, sticks to providing high performance automatic knife gate valveat a very attractive price. As a knife gate valve factory, knife gate valve supplierand knife gate valve manufacturer, we offer pneumatic knife edge gate valve and pneumatic penetrationing knife valve. It is suitable for slurry, powder and granular materials, fibers, and other difficult to control fluids. The bottom of the gate plate bevel cutting surface has the function of cutting off the medium, so that the knife gate valve is not easy to be blocked by debris jam, but also scrape the sealing surface of the adhesion, automatic removal of debris, stainless steel gate can prevent corrosion caused by the seal leakage. Suitable for slurry, powder and granular materials, fibers, and other difficult to control fluids, widely used in paper, petroleum, chemical, drainage, food, and other industries. And the bottom of the gate bevel cutting surface has the function of cutting off the medium, can also scrape the sealing surface adhesion, automatic removal of debris, stainless steel gate can prevent corrosion caused by an automatic knife gate valve.

Types of Knife Gate Valves

Pneumatic Knife Gate Valve

The pneumatic knife gate valve is controlled by a pneumatic actuator and uses a pneumatic device to open and close the valve. With a lightweight, simple structure, reliable sealing, long service life, can effectively cut off the advantages of fibers in the medium.

Pneumatic Penetration Insert Valve

The pneumatic penetration insert valve adopts a gate penetration structure, using a pneumatic device to make the stem drive the gate for adaptive reciprocating movement to achieve the purpose of opening and closing the gate.

Knife Gate Valve Function

The sealing surface of the gate can be lifted, which can scrape off the adhesive on the sealing surface and automatically remove the sundries.

The stainless steel gate can prevent seal leakage caused by corrosion, and the fine grinding and polishing treatment can obtain a better sealing effect.

The stainless steel valve body is durable and durable, the actuated knife gate valve body reinforcement design improves the valve body strength, and the double-head screw is used to open and close more quickly.

The group valve body and packing culvert are all precision casting. The valve body is integrally cast by flange type. The material can be selected from 304, 316, 316L, WCB, 2Crl3 according to user needs. The sealing ring is made of PTFE reinforced polytetrafluoroethylene. Corrosion, wear resistance, no slag.

The full-circle DC channel design has no slag and no jamming.

The scientific design of the upper seal stuffing box makes the upper seal safe, effective, and durable.

Short structure length can save raw materials, installation space, and also effectively support pipeline strength.

The triangular bracket saves raw materials and ensures the required mechanical properties.

The guide block on the valve body of the automatic knife gate valve makes the gate move correctly. Extrusion blocks ensure effective sealing of the gate.

The gate valve knife plate has 5 supporting points. When the valve is closed and under back pressure, the valve plate will not be offset.

Knife Gate Valve Sealing Principle

Through the gate closed to the bottom, the gate bevel cutting surface touches the wedge block on the valve body to make the gate close to the sealing surface to play the sealing effect, and the bottom of the gate bevel cutting surface has the function of cutting off the medium, so that the gatevalves are not easy to be blocked by debris jam, can also scrape the sealing surface of the adhesion.

As one of industrial valves manufacturers, we will do our best to meet all the needs of customers.
