JF Ball Valves have a “floating ball”, i.e. the ball rests between two elastic seats and can move only in the longitudinal direction of the valve. Accordingly pressure in the pipes contributes to the tightness of the valve at all times. Precompressed seats provide similar sealing at low pressures. Few movable parts and suitable material minimize the wear, resulting in long service life.
The valves have a circular straight through passage giving minimal flow resistance. Small sizes require little space, and low weight facilitates installation. Operation is effected by use of a lever and 90° turn between open and closed position. Pneumatic, hydraulic and electric actuator can be fitted. We provide renovation kits for all Ballvalves.
