High pressure zero spillage
The enclosed frame pinch valve is our heaviest duty model designed so that the body can withstand full line pressure (designed to PER standards) if the sleeve ruptures. Typically used on high pressure slurry applications (PN40, PN25) such as tailings line, it provides a dual level of protection for the operators & surrounding environment. It has hydraulically powered by opposing cylinders
Protect sleeve from elements
The shrouded frame pinch valve offers the sleeve protection from the elements (especially UV light) and re-directs spillage should the sleeve rupture. This is done by having a large opening (greater than the pipe area) at the bottom and is designed to only redirect the spillage and not to contain it. Suitable for PN10 & PN16 applications.
The open frame pinch valve is offered as the economical pinch valve. There is no compromise on build quality but by removing material used in the shroud or enclosed model, it allows for valve isolation functionality at a more competitive price. Suitable for PN10 & PN16 applications.
In-Situ Sleeve Replacement
In-situ patented sleeve replacement system engineered to replace a sleeve in under 30 min: Very safe system, no crane or rigging required & minimum labour. This comes in two versions:
- High Lift (<ND400) is a vertical design to lift the upper body upwards to provide easy access for sleeve changing.
- Easy Change (>ND400) is a horizontal design with vertical pinch bars and two opposing actuators for sleeve changing.
