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