diaphragm valve / handwheel / pneumatic / electric

BDK™ Diaphragm Valves are designed for water & effluent treatment, desalination plants, power plants, chemicals & process plants, fertilizers and mining. The valves are simple in construction, effective for liquids and gases encountered with corrosion, abrasion, clogging & contamination.

The wide variety of body materials and linings available mean our Diaphragm Valves are designed for use where the process may demand other valves be constructed of exotic and often expensive alloys due to corrosion and erosion. Equally suited to on and off, or flow control applications, a diaphragm valve is designed to handle positive pressures or high vacuum. Due to the wide range of material options it will handle almost all applications within its temperature and pressure ranges (175°C max. and 16 bar max.) and as such is used in almost every industry on both corrosive and abrasive applications. All working parts are isolated from the line media which enhances its reliability. Maintenance is a simple task with the body remaining in the pipe, the valve thus being field serviceable. It has linear flow characteristics which makes it well suited to throttling or modulating duties. On/off and control automation is possible with the use of modern compact actuators and accessories.
