Compact PVC Ball Valves
Compact pvc ball valve is constructed using the molded-in-place method defined in our construction methods blog. Using this unique method, molding the plastic around the ball and stem assembly, provides multiple benefits. A full port ball is used, but there are no seams in the valve from having to add it in from one end. This makes the valve stronger and more compact without obstructing the flow. Compact PVC ball valves are available in threaded IPS (Iron Pipe Size) and slip connections suitable for both Schedule 40 & 80 pipe.

Being a strong and rigid valve, they are ideal in a variety of water supply applications. When looking for an economical valve, a compact PVC ball valve is an excellent choice.

Union PVC Ball Valves
The union designs feature unions on one or both connections to allow in-line maintenance to the valve without having to disconnect it from the pipe. No special tools for maintenance are required as the handle has two square lugs that allow the handle to be used as a spanner wrench. When maintenance to the valve is required, the threaded retainer ring can be adjusted or removed using the handle to adjust the seal or replace the O-rings.

When the system is under pressure, a blocked union will prevent the ball from being pushed out once the union is taken apart, whereas an economy union does not have anything keeping the ball from being pushed out.
