DESCRIPRION:

It is simple structure; good interchangeability and low price. Stem sealing is not easy deformation, so avoids leakage phenomenon. Overall support is good, stable and solid. Use less rubber of seat, so expansion has small impaction and easy to control torque value at an appropriate range. Applying to two pieces of no-sells connection; structure is simple and convenient to be maintained. Butterfly disc owns automatic alignment function and achieved small combination of disc and seat Phenolic back seat is featured such as no loss, tensile, anti-leak, convenient replacement etc. For seat sealing surface and phenolic back as whole as a whole, it can reduce amount of deformation.
