Product Review

This Valterra 700-11F ball valve is made of white schedule 40 PVC (polyvinyl chloride) for strength and resistance to corrosion and mild chemicals, and is suitable for use as an inline valve for connecting two pipes going in the same direction. It has a maximum operating pressure of 150 pounds per square inch (psi), and two 1-1/4" female National Pipe Taper (NPT) threaded connections. This ball valve is suitable for use with landscape and irrigation, pool and spa, aquaculture, and general purpose applications. Ball valves use a spherical disc to control the flow between pipes, tubes, or hoses. Flow is allowed when the hole that pierces the ball-shaped disc is in line with the inlet and outlet of the valve and is blocked when the ball is horizontally swiveled 90 degrees, so that the hole of the ball is perpendicular to the opening of the valve. Ball valves can be referred to as full port or reduced port (also known as regular or standard port) depending on the inner diameter or the valve. A ball valve is full port if the hole of the ball is the same size as the inner diameter of the connecting pipeline (resulting in lower friction) and termed reduced port if the hole of the valve is one pipe size smaller than the pipe, resulting in less flow through the valve than through the shaft of the pipe. Ball valves may have a handle or lever that aligns with the ball’s position (open or closed) for manual operation. They are primarily used in air, gas, liquid, and steam applications. Valterra Products manufactures and distributes valves, hoses, sewer systems, and pool and spa products. The company, founded in 1981, is headquartered in Mission Hills, CA.
