Sanitary Diaphragm Valve – sanitary stainless steel valves and fittings manufacturer

Sanitary Diaphragm Valve with Stainless steel pneumatic actuator

Are you looking for a high-quality, reliable and efficient sanitary valve for your food, cosmetic, pharmaceutical, dairy, beverage or beer brewing industry? Look no further than the SANSUN sanitary stainless steel diaphragm valve with pneumatic actuator and clamp connections.

Our diaphragm valve is designed to provide excellent flow control and can be used for both open/close duties and sampling in various applications, including biological systems, laboratory engineering, and more. It operates pneumatically via a plastic or stainless steel actuator, providing reliable and efficient performance.

The body of the valve is made from ASTM A351 CF3M (1.4435) as default, AISI 316L Forged Body (1.4435), ASME BPE 316L, or 1.4435-BN2 (316L) Fe＜0.5% Forged Body. The seat material for the diaphragm is made from EPDM+PTFE and has the option for a single EPDM, EPDM+PTFE (2-piece), or Viton (FPM) diaphragm. The end connections are butt-welded or sanitary tri-clamp, making it easy to install and use.

The maximum working pressure is normally closed EPDM 87psi (6bar), PTFE 65psi (4.5bar) as default, normally closed EPDM 116psi (8bar), PTFE 87psi (6bar) as an option, and normally open and double action EPDM 116psi (8bar), PTFE 87psi (6bar). The working temperature ranges from -22°F to 302°F/-30 to 150℃ (Depending on Seal Material) (Stainless Actuator) and -22°F to 266°F/-30 to 130℃ (Depending on Seal Material) (Plastic D27Actuator).

The internal finish of the valve is Ra 16 ~ 32µin (0.4 ~ 0.8µm), Ra 25µin as default, while the external finish is Ra 16 ~ 32µin (0.4 ~ 0.8µm), Ra 32µin as default. The pneumatic actuator types are plastic actuator or stainless actuator, and the actuator operation types are normally closed (NC) – air to open and spring to close; normally open (NO) – air to close and spring to open; and air to air (AA) – air to open, air to close. The actuator air pressure is 58 ~ 102psi (4 ~ 7bar).

Our valve also features a unique seal design with no dead angles, an EHEDG certified sealing concept, and a stainless steel bonnet with sanitary internals. It has a sanitary surface finish with Ra < 0.4µm or EP (SF1 and SF4), and a manual handle and pneumatic actuator that are interchangeable. There is also a wide selection of body types to choose from, including U type/T type/Multiport.

All of our valves are 100% hydraulic tested and inspected, and meet the standards of ASME BPE, 3A, DIN, ISO / IDF. We hold certificates for 3A, FDA, and PED 97/23/EC.

In addition, our valve comes with a range of operational options, including plastic handwheel, stainless handwheel, pneumatic plastic actuator, pneumatic stainless steel actuator, electric actuator, and units for intelligent control and indication, such as proximity switches (position sensor), limit stroker, C-top control, and IL-top control (positioner).

Manufacturer of Sanitary Stainless Steel Pneumatic Diaphragm Valve

The working temperature of the pneumatic sanitary diaphragm valve is usually limited by the materials used in the diaphragm and the valve body lining. Its working temperature range is about -50～175℃. The imported diaphragm valve has a simple structure, consisting of three main parts: valve body, diaphragm and bonnet assembly. The valve is easy to quickly disassemble and repair, and the replacement of the diaphragm can be completed on site and in a short time.
Pneumatic sanitary diaphragm valve is a special form of shut-off valve. The difference from other valves is that it adopts a structure without a stuffing box; the rubber diaphragm can completely isolate the corrosive medium in the flow channel from all driving parts. So as to eliminate the disadvantages of “running, leaking, dripping and leaking” of the usual valves.
Replace the valve core assembly with a corrosion-resistant lining and a corrosion-resistant diaphragm. The pneumatic sanitary diaphragm valve body is made of cast iron, cast steel, or cast stainless steel, and is lined with various corrosion-resistant or wear-resistant materials, diaphragm rubber and polytetrafluoroethylene. The liner has strong corrosion resistance and is suitable for the adjustment of strong corrosive media such as strong acid and strong alkali.

Factory of Sanitary Diaphragm Valve

The structure of the sanitary diaphragm valve is quite different from the general valve. It is a new type of valve and a special form of cut-off valve. Its opening and closing part is a diaphragm made of soft material, It is separated from the inner cavity of the valve cover and the driving parts, and is now widely used in various fields.

The sanitary diaphragm valve is equipped with a flexible diaphragm or combined diaphragm in the valve body and the valve cover, and the closing part is a compression device connected with the diaphragm.

The valve seat can be a weir shape or a pipe wall that directly leads to the flow channel. The advantage of the diaphragm valve is that its operating mechanism is separated from the medium passage, which not only ensures the purity of the working medium, but also prevents the possibility of the medium in the pipeline from impacting the working parts of the operating mechanism.
