As part of our internal technical development programme we ask our experienced Product Development Managers to complete ‘Field Diaries’, documenting the common application questions that they are frequently asked by engineers onsite.
This is also great information to share with our customers!
Can Plug Valves be used in clean water applications?
The answer is now YES! Since recently achieving the WRAS Material Approval for the EPDM compound used in the Val-Matic ‘Swing-Flex’® Resilient Hinge Check Valve, there is now the option for producing an eccentric plug valve with BS 6920 compliant wetted parts.
Plug valves can be used in clean water applications
The Val-Matic ‘Cam-Centric’® eccentric plug valve meets WIMES 8.09 with BS 5158 approval and has dedicated shaft seals in the form of the Val-Matic Grit-Guards™.
Features of the Plug Valve
The flow characteristic of the Val-Matic plug valve with rectangular port makes it ideal for consistently reliable and accurate proportional control of fluids with a reduced potential for cavitation in comparison with a typical Butterfly Valve. The ¼ turn eccentric nature of the shaft and plug design ensures no contact with the valve seat during modulating operation so the torques and wear are minimal providing extensive trouble free performance and whole life cost savings.
