Diaphragm valves are a practical choice for industrial pipelines where the valve operating mechanism needs to remain separated from the process medium. Their flexible diaphragm helps control or shut off the flow through the valve body.
Ultra Valves Automation Pvt. Ltd. welcomes enquiries for industrial diaphragm valves, including screwed-end and flanged-end weir-type designs, from buyers in Mumbai and across India.
Explore the available body materials, diaphragm materials, sizes, connection options and manufacturing standard before choosing a diaphragm valve for your application.
A diaphragm valve uses a flexible membrane to control the passage of fluid through the valve body. In a weir-type design, the diaphragm moves toward a raised weir to reduce or stop the flow.
One of the important characteristics of this construction is the separation between the process medium and the operating mechanism. This makes diaphragm valves worth considering for suitable chemical, water treatment and industrial process applications.
Buyers looking for a diaphragm valve supplier should pay particular attention to the compatibility of the body material and diaphragm material with the process fluid. The diaphragm is a working component and must suit the expected pressure, temperature and chemical conditions.
Ultra Valves Automation Pvt. Ltd. provides a contact point for buyers comparing industrial diaphragm valves for projects in Mumbai and throughout India.
The supplied range includes two weir-type diaphragm valve connection options: screwed and flanged. Both use a flexible diaphragm to regulate or isolate flow.
The screwed diaphragm valve features a weir-type construction with NPT or BSP threaded end connections. This connection arrangement may be considered for suitable smaller-bore process piping applications.
The listed size range is ½″ to 2″, with body material options including CI, CS, 304, 316, PP and PVC.

Technical note: The tables reproduce the supplied specifications. Pressure ratings, temperature limits, actuation options and detailed dimensional data were not provided. Confirm these details, along with chemical compatibility and the approved datasheet, before selecting a valve. The listed diaphragm materials are alternatives, not interchangeable for every service.
The weir-type diaphragm valve construction offers a distinct method of flow control and shut-off compared with conventional metal-seated valve designs.
A flexible diaphragm moves toward the weir to restrict or stop the process flow.
The diaphragm separates the process medium from the upper operating mechanism under normal conditions.
Listed body materials include cast iron, carbon steel, stainless steel, PP and PVC.
Nitrile, Neoprene, EPDM, Hypalon, Viton and PTFE are included in the supplied range.
Screwed and flanged options provide different installation arrangements for process piping.
The raised weir provides a seating surface against which the diaphragm closes.
The diaphragm of valve construction acts as a flexible barrier and closing element. Its movement changes the available flow passage.
The diaphragm is lifted away from the weir, allowing the process medium to pass through the valve body.
The diaphragm moves toward the weir and reduces the flow passage. Whether the valve is suitable for throttling depends on its specific design.
The diaphragm presses against the weir to close the flow path, subject to the valve's design and operating limits.
The phrase diaphragm valve is used for several different products. Some use a diaphragm directly to isolate process flow, while others use a diaphragm inside a pressure regulator, actuator or control mechanism.
Industrial diaphragm valves commonly use a flexible membrane to isolate or regulate flow. The supplied product range includes weir-type screwed and flanged constructions.
An air actuated diaphragm valve uses pneumatic pressure to move the valve mechanism. An air pilot operated diaphragm control valve may use a pilot arrangement to influence valve operation. Actuation availability must be confirmed separately.
A diaphragm operated process control valve uses diaphragm movement as part of its operating mechanism. The diaphragm in control valve systems may also be part of the actuator rather than the wetted shut-off element.
A diaphragm pressure control valve, diaphragm regulator valve or pressure reducing valve diaphragm type uses diaphragm movement to help respond to pressure. A diaphragm type pressure reducing valve and diaphragm operated pressure reducing valve are related descriptions, but their operating details vary.
A gas valve diaphragm or diaphragm gas valve may be used in a gas regulation mechanism. A steam diaphragm valve must be selected with particular care for temperature and diaphragm compatibility. These applications require specific technical verification.
A diaphragm pressure relief valve, diaphragm back pressure valve and diaphragm pulse valve perform different duties. A double diaphragm valve or diaphragm pump check valve may also refer to equipment outside a standard weir-type process valve range.
Buyers sometimes search for a 3 inline valve diaphragm, 3 way sanitary diaphragm valve or 4 diaphragm valve when looking for a particular connection arrangement, port configuration or equipment component.
These descriptions do not automatically refer to the same construction as the two-way weir-type valves listed on this page. Port count, valve size and hygienic requirements should be stated clearly in the enquiry.
Terms such as diaphragm gate valve and diaphragm globe valve may also appear in searches. However, conventional gate, globe and weir-type diaphragm valves have different internal constructions and should not be treated as equivalent.
The diaphragm of control valve actuation systems may serve a different purpose from the flexible diaphragm of a weir-type isolation valve. Identifying that difference helps avoid ordering the wrong product.
Diaphragm valve standards help buyers identify the intended construction and connection requirements. The manufacturing standard supplied for both screwed and flanged weir-type diaphragm valves is BS 5156.
Screwed valves are listed with NPT and BSP connections. Flanged valves are listed with ANSI B16.5, Table D, Table E and DIN 2533 connection references.
Selecting a diaphragm material is particularly important. Nitrile, Neoprene, EPDM, Hypalon, Viton and PTFE have different chemical resistance and temperature characteristics. The most suitable option depends on the actual process medium and operating conditions.
For specialised hygienic, corrosive or high-temperature applications, buyers should request the applicable product datasheet and confirm all relevant service limitations.
