Frequently Asked Questions
Which lining should I specify for the medium in my pipeline?
The page lists PFA, PTFE and FEP among the lining options. Send the medium, concentration, operating pressure and temperature and request confirmation of the lining and all wetted components for your order. The listed materials are alternatives, not a statement that they suit the same chemicals or conditions.
Will the worm gearbox be accessible in my installation?
Provide the valve location, required operating position and available handwheel and maintenance clearance. Ask for the selected valve and gearbox drawing before finalizing the piping layout.
What connection details do I need to include in my inquiry?
Identify the required size, mating flange specification and facing, together with the selected lining and operating conditions. The page lists several flange configurations; confirm the one required for your order rather than assuming interchangeability.
