Diaphragm Valve

Industrial Diaphragm Valve

AMAR VALVE INDUSTRIES is one of the leading Manufacturing High Quality Industrial Valves company in India with Brand Name of GUJCON, BAJPAI & VICTOR..

Custom Valve Solutions provides complete field services at your facility including preventative maintenance, turnaround services, and emergency call-outs.

Amar Valve Industries manufactures a comprehensive range of Diaphragm Valves in sizes 15mm to 300mm and in ASME classes from 150#. The valves are offered in combination of size, pressure class, material of construction, end-connection, etc., to suit myriad applications in process plants, utility lines and HVAC

There are two main categories of diaphragm valves: one type seals over a "weir" (saddle) and the other (sometimes called a "full bore or straight-through" valve) seals over a seat. In general, straight-through diaphragm valves are used in on-off applications and weir-type diaphragm valves are used for control or throttling applications. While diaphragm valves usually come in two-port forms (2/2-way diaphragm valve), they can also come with three ports (3/2-way diaphragm valves also called T-valves) and more (so called block-valves). When more than three ports are included, they generally require more than one diaphragm seat; however, special dual actuators can handle more ports with one membrane.

Technical Specifications

For high purity applications, the design of the basic weir-style diaphragm valve seal presents a number of issues for process engineers working in the biotechnology and pharmaceutical industry. In typical configurations, a weir in the valve body rises in a fluid path and when the valve is closed, the diaphragm meets the weir to shut off the flow. While the technology is intended to reduce turbulence and shear, weir-style valves present a number of issues,

Applications

There is not one single valve type suitable for use in every service, and this holds particularly true for control applications. Over specification is incredibly wasteful and the performance accuracy of the installed control valves should exactly match the required degree of control. The diaphragm valve has been presented as a viable alternative to “traditional” control valve technology, where the strengths of the diaphragm valve as an on/off valve can be equally applied in control applications:

• Suitability for use on corrosive/abrasive fluids (wide range of diaphragm and lining options)
• Leak tight shut off even with solids present
• Relatively low cost (both purchase price and ownership costs)
• In-line maintenance capabilities
