Profile: AKO UK Ltd provides pneumatic pinch, pressure relief, and hand operated pinch valves, including aeration products. Flanged pinch valve works by the controlling medium of air pressure or water being used between the pinch valve body & the sleeve to give 100% closure of the pinch valve. Exhausting the pressure causes the pinch valve to open & when open the sleeve is a true bore allowing unobstructed medium to flow through. Hygenic pinch valves offer special TRI-clamp, IDF & RJT fittings on a smaller socket type pinch valves. We also offer stainless steel spigots for the flanged type pinch valve & weld the special connection to the the existing socket from the outside ensuring the pinch valve still has a true and full bore. Atex pinch valves are used in potential explosive environments. The valve is physically similar to the standard pinch valve, but the only visible differences are the lock teeth washers & the earth connection. The washer teeth are used on the flange bolts to give full contact to the aluminum body through the paint & this ensures the electrical current to pass through the pinch valve.
