Pinch valves for slurry handling
Our standard slurry pinch valves are avaliable in sizes from 25mm to 500mm with pressure ratings from 1600kPa to 2500 kPA. We can provide larger sizes and higher working pressures if needed.
Features include:
- Cost effective
- Light weight
- Fully enclosed spindle
- Suitable for all types of actuators
- Rubber sleeves available in a wide range of polymers
- Maintenance friendly
- Field-replaceable sleeve
- Same face-to-face dimensions as diaphragm valves
Our slurry pinch valves are finished with a powder coat. Electroplating, galvanising and other finishes are also available.

Knife gate valves for slurry handling
We supply a range of knife gate valves for slurry handling in sizes from 80mm to 500mm.
Features include:
- Seats flush so no bottom cleaning door is required.
- Simple gland arrangement allows field service and adjustment.
- Wafer pattern means lighter weight construction in comparison with conventional gate valve leading to easier installation and lower costs.
- Resilient seal seat allows high operating cycles and leak-tight performance.
- Carbon steel valve which is standard construction results in more robust and mechanically stronger valve.
- Stainless steel spindles and blade.
- Simple robust yoke allows for easy fitting to pneumatic, hydraulic and electric actuators.
- Standard actuators available with positioners and position indicators.
- Rubber lining allows valves to be used on slurry applications.
- Roktuf body for high abrasion resistance.

Resilient seal slurry gate valves
Resilient seal slurry gate valves are based on proven and readily available resliant seal gate valves. They are full bore with no flow restriction and comply with SANS 664 and 665 (equivalent to BS 5150).
Moving parts such as Gate, Spindle, and thrust bearings can be reconditioned in line.
Features include:
- Rugged design
- Oval body to prevent distortion
- Long body guides to ensure positive travel of wedge
- Kidney shaped bonnet seal
- Parts are interchangeable
- SG (Spheroidal Graphite Iron) castings
- Bodies are lined with specially formulated abrasion resistant rubber
- Taper seal design ensures that entrapped foreign objects do not affect the valve sealing
- Working Pressures up to 2500 kPa
- Drop-tight from 0 to maximum design pressure
- Rising spindle design
- Ball thrust bearings as standard on valves DN 350 and larger
- High tensile stainless steel cold rolled threaded spindle
- Flanged end connections drilled to customer requirements
- Body linings available in various materials to suit media
- Ball thrust bearings on valves DN 150 to DN 300
- Dome type position indicators
- Gear boxes for reduced operating force
- Actuation: electric, pneumatic, hydraulic

Ball valves for slurry handling
The Valvtron extreme service ball valve is designed for the most abrasive applications and high temperatures. It is available in sizes from 25mm to 400mm.
Valvtron metal seated ball valves are made in South Africa. They cost less than similar imported valves and we offer a rapid-turnaround repair and maintenance service.
We see them as a suitable replacement for imported valves like those supplied by Mogas or Valve Technologies.
