Pinch Valve Design – What makes it?
Pinch Valves (also commonly nicknamed as squeeze valves, bladder valves, rubber hose valves, soft seated valves, hose valves or shut off valves), are made up of only 3 components.
These include the housing or body, end connections, and a rubber sleeve that fits inside.
Pinch Valve housing material options include:
- Stainless Steel
- POM (Polyoxymethalene)
The rubber sleeve is fitted into the Pinch Valve housing. This is achieved simply by the addition of some lubricant paste, and for larger sizes from DN100 upwards, a fitting kit can be used which consists of a mounting pipe, mounting board, lubricant paste, and assembling nuts & bolts.

End Connections for a Pinch Valve Design
The extensive different types of end connections available for an AKO Pinch Valve design make almost every application possible. These include:
- Flanges (DIN PN10/PN16 or ANSI Class 150)
- BSP screwed sockets with internal thread
- Threaded spigot
- Weld-on ends
The end connections are bolted or screwed into place, making the Pinch Valve ready to be fitted/installed into it’s required industry of application.
