The Oteco Model 72 gate valve is designed for the oilfield and is the proven, reliable choice for applications requiring up to 5,000 psi working pressure and temperatures up to 250° F (121° C). Features: The use of Body Subs allows change out of valve connections without changing valve body or entire valve. Full rising, one piece forged gate and stem displays current valve orientation: open, partially open, or closed. Extra-large ball bearings and heavy duty stem threads minimize torque required for valve operation. Proven interlocking gate packing and wear plate design protects the valve body and cap during repeated valve opening and closing. Standard gate packings are designed for a wide range of fluid environments. Model 72 parts are interchangeable with Cameron type ‘S’ Flex-Seal valve parts.
