Diaphragm valves

Diaphragm valves of the highest quality made from PVC-U, PP and PVDF

There are different diaphragm valves under taps and valves in the RCT-online shop. In pharmaceutical technology, process technology, chemical technology and laboratory technology, pneumatically controlled and hand-controlled manual diaphragm valves are used as standard elements in process operation. A valve of this type with a diaphragm is used to convey aggressive media, as well as aggressive gases. Another area of application for the valves is also measurement and control technology and chemical process technology, but valves of this type are also used in preparative laboratory technology.

Manual diaphragm valves

The hand-controlled diaphragm valves are available in PVC-U, PP and PVDF versions. All the types are characterised by high mechanical strength and above-average temperature resistance. The maximum operating pressure can be specified for a diaphragm valve of this type as 10 bar at +20°C. The manufactured sizes are determined by the nominal sizes. The range of available manual types is wide. The nominal sizes DN 15, 20, 25, 32, 40 and 50 should be mentioned here. All the manual valves mentioned are extremely robust and powerful.

PVC-U

Manual valves made from PVC-U are particularly flexible in their installation and allow a temperature range of -10°C to +60°C depending on the respective membrane which is used. On the one hand, the connections to the diaphragm valve are secured by adhesive connectors. On the other hand, RCT offers manual valves made from PVC-U with fittings combined with solvent cement sockets as well as with GRP flanges, which are also suitable for operation at higher pressure.

PP

The installation method of the PP manual valves is discretionary. The max. pressure for a valve of this type is 10 bar at +20°C. The maximum temperature of the flow body or housing body for a diaphragm valve of this type is +80°C.

Pneumatic diaphragm valves

Diaphragm valves with pneumatic actuation are manufactured from the materials PVC-U, PP and PVDF. The control function for a valve of this type is spring-closing (NC, "Normally Closed") and spring-opening (NO, "Normally Opened"). Pneumatic valves with the function: double-acting (DA) are available as a further control function. The maximum control pressure is 7 bar.

PP and PVC-U

In addition, RCT offers diaphragm valves made from PP (polypropylene), which are pneumatically controlled, and whose characteristics and areas of application absolutely coincide with those made from PVC-U.

PVDF

Reichelt Chemietechnik provides pneumatic diaphragm valves made from PVDF for critical media, which have their place in chemical engineering, process engineering and process technology.
