Frequently Asked Questions
Will the disc be lined, or will the medium contact stainless steel?
The page describes a stainless-steel disc and a lined-disc alternative. Specify the required wetted-material arrangement and request confirmation of the body lining, disc and seals for your chemical and operating conditions.
How do I specify the required action if the air supply fails?
State the required failure position and operating conditions and ask for confirmation of the actuator and pneumatic circuit. The available single-acting and double-acting descriptions do not by themselves establish the response of the complete installed assembly.
Are position feedback and manual operation included in the quoted assembly?
The page describes feedback and manual-operation options. Identify which accessories you require and request the assembly drawing and scope of supply, including the operating and control arrangement, before ordering.
