W Tubing Retrievable Safety Valve

The W Tubing-Retrievable Safety Valve (TRSV) is used in general production completion to shut in a well at a point below the surface. The valve contains a piston, opposed by a compression spring and the well pressure, which operates a flapper mechanism. When pressure is released from the piston chamber, the spring moves the piston up and the torsion spring rotates the flapper to the “closed” position. The simple, compact design enhances the valve’s overall reliability while featuring an economical price.
