Avail our offered Gate Valve Class 600 that is used in the several industries for controlling the flow of liquids and gases. Basically, it is a piping apparatus that contains a metallic disc responsible for blocking and allowing the flow of fluids. When this disc is perpendicular to the flow, it does not allow the fluid to pass. One can change the placement of the disc by rotating its knob to allow the fluid to pass. Since it is made of the high-quality material, Gate Valve Class 600 conveniently resist the corrosion and abrasion due to chemical attacks.
SALIENT FEATURES
Body : Robustly designed to withstand stringent duty condition, Smoothly configurated to reduce Turbulence.
Long and Accurate Guides : Optionally toleranced for free movement of wedge in flow path and retaining leak tightness even in fluctuating line condition.
Super Finish Seating Faces : High accuracy and super finish 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 extreme accuracy and finally ground and lapped to a mirror finish to secure no-leak condition and to minimize the risk of galling.
