08/07/2019· The Atval technology is developed in South Africa in conjunction with the local mining industry, which requires valves to handle slurries at higher pressures than anywhere else in the world. The pinch valve is an ideal product for this application because of its full unrestricted flow pattern and the use of gum rubber as an abrasion resistant closing membrane.
Corflex Engineering in South Africa have been building pinch valves for the slurry pipeline industry since 1981. Today the company manufactures pinch valves for pressure ranges from low to high. Corflex supply pinch valves suitable for
Corflex Pinch Valves are totally manufactured in South Africa. All Corflex STD, HD XHD Pinch Valve Sleeves 150mm and larger are pressure tested to twice the recommended working pressure with an excess of 3:1 safety factor. A serial number is on the sleeves and an Inspection and Test Certificate is supplied for each sleeve.
Open Frame Pinch Valve. Closed type pinch valve protects the sleeve from any harmful radiations and in the case of its rupture the closed body prevents the media spillage. Suitable for high pressure applications. Products Range: Size: DN40 to DN 700. Type: closed type. Pressure Rating: PN 10 PN 40.
Due to the materials of construction, the operating torque is less and the cost of actuating the valves is therefore drastically reduced. CLAMPON Slurry Pinch Valves are installed in every mining application in South Africa, and are constantly outperforming its competitors
Mechanical float valve used to automatically control the levels in tanks and reservoirs and used in the water, mining and agriculture industries. Size range: DN15 to DN200. Pressure ratings:
The Corflex Pinch Valve has an excellent resistance to abrasion and because of this it is ideal for use on slurries. When fully open it is similar to a straight through rubber lined pipe and when closed gives complete isolation. Turbulence is minimal thus greatly increasing the life of the valve The valves are not subject to scaling.
Uses On All Types of Slurries. Pinch valves have long been recognised as ideal for use in the hydraulic transport of solids in pipelines but have in the past been restricted in their use because of their relatively low working pressures. The Corflex Pinch Valve has an excellent resistance to abrasion and because of this it is ideal for use on slurries.
