Ravands controls manufactures and offers non-return valves that have a unique sealing design for long life and seals at low pressures. A smart seal enables ball to seat easily and position itself for better seal. Area for the flow between the ball and the body is more than the orifice area and hence minimum pressure drop takes place. The non-return valves can be mounted in horizontal or vertical position. Ball struck is totally avoided by special design of guides. These non-return valves are true union version so that the downstream pipeline can be disconnected for any maintenance without disturbing the upstream. The non-return valves are available in chemcom and flowcon series. Chemcon is used for chemical applications and flowcon is for water and general purpose applications.
