Pneumatic ANSI and DIN Lugged Industrial Knife Gate Valve with Large Overall performance
The Lug knife gate valve is a uni-directional wafer valve for basic industrial software.
The nominal diameter offered assortment from DN50 to DN600 with Lugged flange connections complying with EN 1092-1 PN10/PN16 or alternatively, ANSI B16.5.
The knife gate valve is predominantly employed in the paper and pulp, chemical, and mining industries, andthe foodstuff sector as properly as sewage treatment crops, and in the sugar, steel and animal feed sectors.
Travel actuators offered for the knife gate valve consist of handwheel with climbing or non-rising stem, or alternatively double-or single-acting pneumatic cylinders (spring return), Bevel Gear, chain gear and electric actuators.
The composition of the uni-directional knife gate valves is a wafer style ca EPT monoblock entire body, with raised experience and strengthened ribs for bigger nominal diameters for added body toughness.
The monoblock entire body of the knife gate valves is offered in both WCB or alternatively in stainless steel CF8M/CF8/CF3/CF3M.
The slide plate of the knife gate valves is using stainless steel AISI 304,201,301,304L, 316L or AISI 316 or else. The plate radius of the knife gate valves slide gate has a bevelled slicing edge. As a outcome, solids can be minimize via, attaining a tight seal in the shut position. On request, the thickness of the knife gate valves plate can be improved for greater working pressures and/or larger good quality substance can be used.
The slide plate’s seat in the monoblock body is sealed tight by an elastomer seal in Physique groove or Metallic to steel sealing.
The standard content employed for the knife gate valves elastomer seal is EPDM/ NBRor Steel seat
Alternatively, nitrile, viton, PTFE or else are obtainable.
The gland packing consists of a number of levels of braided fibre.
An EPDM o-ring is furthermore integrated into the levels of the knife gate valves gland packing as normal if reque EPT by consumers
Tests contains a entire body shell take a look at, a seat te EPT and a cycling te EPT to insure appropriate working of shifting components.
Standard Shell test: Hydro te EPT at 1.5 moments the rated CWP (chilly doing work stress) Zero allowable leakage
Normal Resilient Seat test: Hydro te EPT at 15 psi (1 bar) and rated CWP
