ABSTRACT:
A valve is provided with improved bonnet-stem and bonnet-valve body seals. Both non-metallic seals may be simultaneously compressed by threading the bonnet to the valve body, with a valve stem seal sandwiched between the bonnet and an axially movale retainer in engagement with the valve body. A jam nut threaded to the exterior of the bonnet may be periodically loosened, and the bonnet further threaded to the valve body to re-compress both seals and stop leakage from the valve. The concepts of the present invention are well adapted to providing a low cost valve suitable for handling corrosive fluids.
