Versatile Material and Connection Options

Choose from robust body constructions (Glass Lined, PP Lined, Stainless Steel, Cast Iron, and Plastic), and diaphragms tailored for diverse applications. The valve is available in a range of end connections including screwed, flanged, butt weld, and socket weld, allowing easy integration into new or existing piping systems.

Reliable Performance in Demanding Environments

Designed to deliver consistent and safe operation when dealing with water, chemicals, or steam, our diaphragm valves are soft-seated for superior sealing and longer service life. They function efficiently under pressures up to 10 Bar and temperatures reaching 120C (depending on materials), making them suitable for a wide scope of industrial uses.

Ease of Operation and Compliance

Valves are standardly operated manually via handwheel, with options for pneumatic or electric actuation. They feature a full bore to minimize flow resistance, ensuring low pressure drop. All valves meet relevant industrial and sanitary standards, supporting both horizontal and vertical installations for maximum convenience.

FAQs of Diaphragm Valve Straight:

Q: How do I select the appropriate diaphragm and body material for my application?

A: Selection depends on the media and operating conditions. For corrosive chemicals, glass lined or PP lined body with PTFE or EPDM diaphragm is recommended. For water and air, EPDM or Nitrile diaphragms work well. Consult the manufacturers specification to match the valve to your process requirements.

Q: What are the main benefits of using a Diaphragm Valve Straight in my system?

A: Diaphragm Valve Straight offers reliable sealing, full bore flow for minimal pressure drop, and excellent resistance to aggressive media. Its design supports frequent operation and long service life, making it ideal in sanitary and industrial processes like water treatment and chemical processing.

Q: Where can these diaphragm valves be installed within a piping setup?

A: These valves can be installed in both horizontal and vertical piping arrangements. Their adaptable design and range of end connections ensure compatibility with various system configurations common in industrial facilities.

Q: What is the process for maintaining or replacing the diaphragm in these valves?

A: Maintenance typically involves isolating the valve from the system, removing the actuator or handwheel, accessing the diaphragm chamber, and then replacing the diaphragm with a suitable spare. Routine checks ensure optimal performance and longevity.

Q: When should I consider manual versus automated actuation for these valves?

A: Manual actuation via handwheel is standard and suited for applications where frequent adjustment is not required. For processes needing remote or automated control, pneumatic or electric actuators can be requested as an upgrade.

Q: What standards do these diaphragm valves comply with?

A: The valves meet major international standards such as DIN, ANSI, and BS, depending on the manufacturer specification. This ensures compatibility and safety across a wide range of industrial sectors.
