Overall view of Sangyie Technology's regulating diaphragm valve

Regulating diaphragm valve ASME BPE, 316L Stainless Steel

SY-DV22

Sangyie Regulating diaphragm valves are widely used in fluid control systems and achieve remote automatic control. The intelligent positioner is a valve opening regulator based on microprocessor control. Opening of the valve can be set by external input singnals. Sangyie Regulating diaphragm valves are perfect used for food and biopharmaceutical as well as semiconductor ultrapure industry, microelectronics industry and fine chemical industry.

Regulating diaphragm valve Operating principles

● The diaphragm of Regulating diaphragm valve provides the body seal as well as the seat seal. There are no paths to the outside environment, so the valve is suitable for Regulating processes.

● When the valve is being closed, the pressure pad which supports the diaphragm is being moved towards the sealing face of valve body. When the pressure plad is being moved towards the sealing face of valve body, the diaphragm is being flexed and is forced down onto the seat area in the centre of valve body, thus, the valve is closed.

● Mutual relation between valve body and pressure pad prevents over compression to the diaphragm.

● Regulating diaphragm valve can be opened or closed either manually or pneumatically, also by control unit and solenoid valve.

Regulating diaphragm valve Techinical features

● Excellent for flow control and sterile applications

● Easier to be cleaned up, comparing to other valves

● Perfect used for media with particles

● Less cavitus when used for flow control

● Valve body and diaphragm are available in different materials and versions

● Cavity free and self-draining

** In order to achieve perfect self-draining, for long pipeline, the valve is suggested to be installed by α° as below to make sure complete self-draining in the whole system.

Regulating diaphragm valves, Sanitary Regulating diaphragm valves, Hygienic Regulating diaphragm valves, sanitary valves, hygienic valves, SS valves

● Valve body and diaphragm are available in different materials and versions

● Sealing between lug boss around the valve body and raised ribs at corresponding position of the diaphragm ensure the diaphragm can be sealed well with valve body either the valve is opened or closed. As a result, the valve can be drainable completely and can be cleaned easily, meeting EHEDG design standard.

● Available in all common connection sizes and variants integrated locking

● Minimum and maximum stroke limitation

● Production process complies with ASME BPE, 3A, DIN, ISO sanitary valve norms

Intelligent positioner Techinical features

● Compact structure and small contour, better satisfying space limitation

● Stable and reliable performance

● Sensitive response

● Large-screen LCD display

● Easily operating

● Standard electrical interface, convenient wiring

● Accurate adjustment

● Strong anti-interference ability

● Spring pop-up feedback lever, easily to be installed

● Kinds of interfaces for different diameters
