<p>A valve packing compression apparatus and method of use therefor are disclosed for compressing packing rings into a stuffing box of a valve bonnet which has a gland follower. The compression apparatus includes a base plate configured to support and consistently position the valve bonnet. A rocker arm is pivotally attached to the base plate. A hydraulic ram is also attached to the base plate and extends to contact one end of, and thereby pivot, the rocker arm. The opposite end of the rocker arm includes a pair of tines which straddle a yoke support arm of the valve bonnet and align with the gland follower. Hydraulic fluid is provided to the ram by a hydraulic pump through a pressure regulator. When the hydraulic ram is activated to extend, the tines contact the gland follower, thereby compressing the packing rings a predetermined amount.</p> |
