Frequently Asked Questions
What is a straight diaphragm valve used for?
Straight diaphragm valves are used for on/off and throttling control of fluids in piping systems. In marine applications, they are commonly employed in seawater cooling lines, bilge systems, ballast water management, and chemical handling circuits where a leak-proof seal is critical.
What diaphragm materials are available?
We offer EPDM, PTFE, and Nitrile diaphragms. EPDM provides excellent resistance to seawater and weather; PTFE is ideal for aggressive chemicals and high temperatures; Nitrile is suitable for oil and fuel applications.
Can this valve handle seawater?
Yes, the straight diaphragm valve is specifically designed for marine environments. The combination of a corrosion-resistant body (cast iron or stainless steel) and an EPDM or PTFE diaphragm ensures reliable performance in seawater service.
What is the maximum pressure rating?
The valve is rated for PN10 or PN16 depending on size and material configuration. For specific pressure requirements, please contact our technical sales team.
