This Ball Valve is a valve that can handle severe shock loads and misalignment. The stress is absorbed by the valve body, not the ball and seat. The design minimizes the chance of uneven wear and leakage. NDS Flow Management offers a range of specialty fittings. From expansion repair and compression couplings, to spring, swing check and ball valves, we offer a full line of products for irrigation, plumbing, pool and spa, and industrial applications.
