Valves for slurry of the pinch/squeeze closed type are the best solution for automatic shut-off, in particular with use on dust, suspension materials, sewage, air venting, slurries, sand, powders etc.
They come with a variety of choice for the end connections either side of the body, which include tri-clamps, weld-on ends, threaded spigot, Flanged PN10/16, ANSI 150 flanged, internally threaded BSP sockets, RJT connections, and threaded hose nozzles.
These wide range of connection options broaden the industrial applications where valves for slurry will be suitable for controlling the flow of product.
Valves for slurry with a pinched closed rubber sleeve are extremely robust and wear free. The only wearable part is the internal rubber sleeve, which only needs replacing after a high number of years in many slurry applications.
Valves for Slurry Silo Protection Systems
Valves for slurry sites where the operation of filling from road tankers takes place can cause damage to silos and their accessories. Normally this is caused by over filling or excessive pressurisation.
It is the responsibility of the user to prevent over pressurisation in the form of a silo safety system. There is a unique designed pinch valve with a specially manufactured solenoid valve on the market for this process.
This type of valves for slurry will fail closed with loss of air or power. With a regular maintenance plan, bladders can be simply changed before they fail. These valves for slurry allow the quickest filling time due to lack of obstructions.
Valves for Slurry Temperature Range
Valves for slurry sometimes operate with high temperatures being exposed to the rubber sleeves, so the rubber hoses are routinely replaced at intervals by an engineer.
It is important that the correct sleeve material is used for any application, taking into account the temperature range for each material. For example, natural rubber is rated to 80 degrees C, whereas EPDM is rated higher to 120 degrees C.
