*********0psi ***3/*6" to **1/*6"
The wellhead gate valve wholesale 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
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
