 GAOCHUAG knife gate valve is a bi-directional wafer valve for media of substantial regularity.

The nominal widths CZPT for the knife gate valves selection from DN050 to DN600 with flange connections complying with EN 1092-2 PN10 or alternatively, ANSI B16.5.  

The GAOCHUANG knife gate valve variety B is predominantly utilised in the paper and pulp, and chemical industries, in water treatment method, energy generation and energy station technological innovation.  

Travel variants for the knife gate valves incorporate a manually actuated handwheel design with climbing or non-climbing stem or double-acting pneumatic cylinders and electrical actuators.  

The structure of the bi-directional knife gate valves encompasses a two-component wafer fashion body screwed with each other, with strengthened ribs for greater nominal diameters for added body energy.

The two-portion wafer fashion body of the knife gate valves is CZPT in grey solid iron (GG25) or alternatively in stainless steel AISI 1.4408 (CF8M).

The stainless metal entire body of the knife gate valves is also fitted with internal sliding strips produced out of UHMW polyethylene to enhance closing and opening traits.

The slide plate of the knife gate valves is produced utilizing stainless steel AISI 304 or AISI 316 as standard.

The knife gate valves slide plate is a single portion with a round opening. When closing, a slice of the item stream is lower off. The slide plate is floor sleek on the two sides to avert jamming and/or maintain seals and gland packing.

On ask for the thickness of the knife gate valves plate can be enhanced for larger operating pressures and/or higher high quality substance can be utilised.  

The two-part, screwed jointly physique and slide plate seat is sealed restricted by an elastomer seal in a stainless metal retainer ring nevertheless, this can also be achieved CZPT the elastomer seal (sealed with metallic).

The regular material utilized for the knife gate valves elastomer seal is EPDM. Alternatively, nitrile, viton, PTFE or silicone ) are CZPT.  

The gland packing consists of a number of layers of braided fibre on each and every side.

An EPDM o-ring is furthermore integrated into the layers of the knife gate valves gland packing as common.

In addition to greased cotton, a PTFE-coated artificial fibre, braided PTFE, graphite, ceramic fibre or Dynapack can be employed as gland packing for the knife gate valves.

Max. operating pressures for GAOCHUANG  Knife Gate Valves:

DN050-DN250: 10 bar
DN300-DN400:   6 bar
DN450:               5 bar
DN500-DN600:   4 bar
