Title: A Camparison Between Compact Pvc Ball Valve And Union Pvc Ball Valve

Blog Entry: 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. Did you know? Compact and union PVC ball valves can be used in both Schedule 40 and Schedule 80 systems as these ratings refer to the pipe wall thickness. PVC ball valves are rated based on pressure not wall thickness allowing them to work for both Schedule 40 and Schedule 80 pipe. The outside diameter of both pipes remains the same, it is the inside diameter that gets smaller as the wall thickness increases. Generally, Schedule 40 pipe is white and Schedule 80 pipe is grey but either color valve can be used in either system. PP clamp is also our products, you can come and buy!
