Since 1969, Spears® Manufacturing Company has developed high-quality thermoplastic piping system components to better meet industry needs. Spears® thermoplastic valves have been developed through years of product improvement testing, combined with the latest in computer-aided engineering and manufacturing technology. Today, Spears® valves are recognized for their quality, reliability, and long service life. Backed by the best in customer service and product availability, Spears® valves are the first choice for use in a wide variety of applications, including Industrial & Chemical Processing, Turf & Irrigation, Pool & Spa, and numerous Original Equipment Manufacture products.

Ball valves derive their name from the on/off function accomplished using a flow-controlling ball located in the center of the valve body. A hole through the center of the ball (valve bore) connects the inlet and outlet sides of the valve for fluid stream transfer. The ball rotates 90° on an axis perpendicular to the fluid stream to block flow in the “off” position. The ball is held in place between two valve seats, which serve as a “bubble tight” seal off while providing lubrication during valve operation. Elastomer O-rings are used in the stem and seal carrier to prevent fluid leakage. Pressure drop is virtually eliminated in the full-open position since the valve bore is the same size as Schedule 80 system piping. The T-Style ball valve is a special configuration incorporating a Tee fitting at one end of the valve. This design maintains proximity of the valve to the fluid main line to minimize the “dead leg” of potential fluid accumulation, where required by the specific application.

Spears offers to customers many kinds of ball valves as below:
