Hydraulic Gate Valve

2000-15000psi 1-13/16" to 7-1/16"

The AQE wellhead valves is available with an optional manual closing and locking screw.

The adjusting nut in the bind cylinder head absorbs the overload or testing pressure applied to the opening side of the valve, protecting the stem from overload.

The cylinder ports are located a sufficient distance from the wellhead systems cylinder head to allow in the piston cover the exhaust port before the end of the stroke. This arrangement provides enough damping to protect the cylinder from shock loading.

The overload or testing pressure applied to the closing side of the cylinder are absorbed when the piston bottoms out against the packing gland of the stem.

The tail rod and the operating stem have back seating shoulders which allow replacement of the stem packing
