ABSTRACT:
A clamp yoke valve has a yoke member engaged with the valve body about its bonnet opening, a bonnet sealing the bonnet opening and including a packing cartridge chamber opening outwardly of the valve body and disposed about the valve stem and a packing gland which is movable axially about the valve stem against the packing in the bonnet member. The packing gland has a multiplicity of teeth about its circumference which are disengageably intermeshed with a multiplicity of teeth in the bore of a gland wrench disposed thereabout. The gland wrench includes a pair of arms extending outwardly of the yoke member to permit rotation thereof and thereby of the packing gland to effect compression of the packing material about the valve stem.
