GATE VALVES

Forged Carbon Steel / Forged Stainless Steel / Cast Carbon Steel / Cast Alloy Steel / Cast Stainless Steel / Cast Iron
SALIENT FEATURES

Body : Robustly designed to withstand stringent duty condition, Smoothly configurated to reduce Turbulance.

Long and Accurate Guides : Optionally toleranced for free movement of wedge in flow path and retaining leak tightness even in fluctuating line condition.

SuperFinish Seating Faces : High accuracy and superfinish by lapping of body ring and wedge seat faces, guarantee zero leak and reduce operational torque.

Deep Stuffing Box : Facilitates extra number of gland packings and ensures pressure tightness and long packing life, can be repacked while valve is back seated.

Spindle-Wedge : T-SLOT is housed in the wedge in such a manner to improve transmission efficiency of torque from spindle to wedge and ensure leak tightness. the solid flexible wedges fitted in Gate Valves are Cast Steel having 13% Chrome Welded seat facings, machined with exterme accuracy and finaly ground and lapped to a mirror finish to secure no-leak condition and to minimize the risk of galling.

Quality : Committed with dedicarion.

Inspection : Third Party Inspection by Lloyds, Bureau Veritas, ABS,UHDE,Bax Council,ElL,PDIL and IBR Etc. are being regularly Carried out against Customer requirements.
