There are many type of PVC Valves. PVC valves are used in systems to control the flow of the media and to allow for repair on the pipe system. The most common PVC valves are true union ball valves, true union check valves, compact ball valves, butterfly valves, gate valves, diaphragm valves, and swing check valves.
The valves range in size for each type but are all pressure tested at 150PSI. PVC Valves are designed to be installed with glue, thread tape or by a flange system. PVC Valves are used in waste water treatment plants, chemical stations, water parks, aquariums, swimming pool, and irrigation applications. These valves are manufactured with EPDM or Viton seals. PVC valves can come in white, gray, clear, schedule 80 and schedule 80 CPVC. Don't see what your looking for? Contact for immediate help!
Step 1 FILTER OPERATION - For the majority of the time your Filter will operate in Filter mode. Water will enter from the pump into the top of the filter, flow through the sand to remove dirt particle and return to the pool from the bottom of the filter. Csi wealth management essentials pdf writer. Over time, the sand in the filter will become clogged with these dirt particles and will have to be cleaned. In Backwash Mode, the water is reversed through the filter.
Water from the pump is fed into the bottom of the filter tank, pushed up through the sand to release the trapped dirt particles and purged out a waste line connected to a port at the top of the Filter Tank. The Hayward Slide Valve is used to reverse the flow of water inside the Filter Tank. Step 3 WATER FLOW, FILTERING - When the Slide Valve is in the FILTER position, water flows from the PUMP into the middle Valve position and up into the upper piping of the Filter Tank. The top diffuser spreads the water evenly across the top of the sand, Then the water is filtered through the sand as it moves to the bottom of the Filter Tank.
Subtitle translation wizard. Here the water is collected into the bottom laterals; pushed up through the lower piping to exit out the lower Valve Port; and returned to the pool. The upper Valve port to the WASTE line is closed off. Step 5 WATER FLOW, BACKWASHING - With the Slide Valve in the Backwash position, water flows from the PUMP through the middle port and down into the lower piping of the Filter Tank. The water is then dispersed into the bottom of the tank through the laterals, then forced up through the sand to the top of the tank. This action separates the debris from the sand and carries it to the top in the water. At the top the water and debris is collected and fed into the upper piping to be diverted out the WASTE Valve Port and Waste Line.
The lower Valve Port, which normally returns waterr to the pool, is shut off.
Applications. FILTER - For normal filtering and regular vacuuming. BACKWASH - For cleaning filter sand bed of accumulated debris.
Swimming Pool Slide Valves
RINSE - Use after completing backwash cycle to ensure all dirty water is rinsed out of the filter to waste. WASTE - By-passes the filter for draining or lowering pool water level and for vacuuming heavy debris directly to waste line. RECIRCULATE - Water is recirculated through the valve, by-passing the filter.
CLOSED - Shuts off the flow from the pump to the filter. WINTER - For winterizing.
