Corflex Engineering (Pty) Ltd. in South Africa have been manufacturing and supplying pinch valves for the slurry pipeline industry since 1981. Today the company manufactures pinch valves for pressure ranges from low to high. Size for size Corflex supply pinch valves suitable for higher working pressure than any other similar valve. Corflex Pinch Valves are used in applications where previously because of pressure only steel valves were used. The pinch valves are very strongly built and wherever they have been installed have generally given an excellent life with little or no maintenance. The reinforced rubber sleeves are built to a very high standard. All the sleeves are pressure tested to twice the maximum recommended working pressure. Corflex Sleeves have an excess of 3:1 safety. Corflex Pinch Valves are extensively installed on major slurry pipelines in the mining and allied industries in South Africa as well as in many other countries around the world. In many instances due to wear, pressure or excessive maintenance Corflex Pinch Valves have been used to replace valves such as Plug, Ball, Gate, Knifegate, Butterfly, Sliding Disk, Diaphragm and other type Pinch Valves. Corflex also developed the Corflex ‘NIPPIT' Pinch Valve range to compete with the traditional rubber lined diaphragm type valve. Corflex Engineering (Pty) Ltd is the sole manufacturer of Corflex Pinch Valves.
