BS EN 13397 Diaphragm Valve, Ductile Iron, DN50, PN10, BSP

The BS EN 13397 Diaphragm Valve Manufacturer produces high-quality weir-type diaphragm valves in compliance with BS 5156 standards. These valves feature a durable ductile iron body, designed for reliability and longevity. Available in DN50 (equivalent to 2 inches) size, they operate at a pressure rating of PN10 and are classified at 150 LB. The valves come with BSP (British Standard Pipe) threaded ends for secure and easy installation.

Product Name: BS EN 13397 Diaphragm Valve
Type: Weir Type Diaphragm Valve
Design Standard: BS EN 13397 (BS 5156)
Body Material: Ductile Iron
Size: DN50, 2 Inch

Our Unlined Screwed End Diaphragm Valve features a Weir Type design with BSPP threaded ends, making it ideal for general industrial applications. This handwheel-operated valve is constructed with a ductile iron body and bonnet, and is equipped with an EPDM or Neoprene rubber diaphragm. The valve closure is achieved through an elastic polymer diaphragm (EPDM), ensuring reliable sealing.
Designed for linear motion, this manual diaphragm valve offers a bolted bonnet and seat-less design, providing a cost-effective, easy-to-maintain solution for a wide range of applications. The bi-directional, Weir Type valve ensures excellent durability and reliability, effectively isolating the line media from the mechanical components of the valve.
Screwed End Diaphragm Valves are commonly used in chemical and water treatment industries due to their low maintenance and easy availability. They are especially preferred in the mining, mineral processing, and fertilizer industries for their ability to handle abrasive and corrosive media. The valve is fitted with a yellow position indicator for clear operational status.
