Threaded Screwed End Diaphragm Valve
Threaded Screwed End Diaphragm Valve Manufacturer
MVS Valve offers a high-performance Threaded Screwed End Diaphragm Valve designed for reliable operation in general-purpose industrial applications. Manufactured in a Weir Type design, this diaphragm valve is built with precision to ensure dependable flow control where threaded connections are required. It features BSPP threaded ends, making it ideal for compact pipelines and low-pressure systems where space and simplicity matter.
This valve is constructed using Ductile Iron GGG40 coated with durable black epoxy, ensuring enhanced corrosion resistance and longer service life. The handwheel-operated mechanism allows for smooth manual operation, and the valve includes a visible yellow position indicator for better user control. The flow is regulated using a flexible EPDM or Neoprene rubber diaphragm, which provides a secure shutoff and reduces the risk of leakage even in extended usage conditions.
The Threaded Screwed End Diaphragm Valve uses a seatless internal design with a bolted bonnet, ensuring ease of maintenance and minimizing replacement downtime. It’s simple linear motion and dependable performance make it a preferred choice in industries that handle non-aggressive fluids, including utilities, water distribution, process systems, and general fluid transfer setups.
