All About The Types of PVC Ball Valves
A PVC ball valve, also known as polyvinyl chloride, is an on-and-off plastic valve with a rotating ball with a bore were moving the ball a quarter turn may halt the fluid flow. They may be used to control the flow of water, air, corrosive chemicals, acids, and bases. They are also very cost-effective and long-lasting. With less mechanical strength, PVC ball valves exhibit outstanding low temperatures and pressure tolerance. PVC Ball Valve halts the flow by turning a ball 90 degrees, like with all ball valves.
A spinning ball known as a rotary ball is at the core of PVC ball valves. The mechanism for spinning the ball is a stem at the top, depending on how the valve is made, either manually or automatically. When the handle is parallel to the pipe, the valve is open; when it is perpendicular to the pipe, the valve is closed.
PVC Ball Valve Types
Automatic Valves
Two or three-way automatic PVC ball valves are available. They have a spring-loaded actuator, an electric or pneumatic one that may be operated manually using a remote, or both. Automatically operated PVC Ball Valve may be used with various media, including water, gas, and oil. The valve’s ball is designed to open or close to release or halt media flow.
Check Valves
PVC ball check valves are employed in filtration and pumping systems where backflow might harm the system or introduce pollution. They function as a pressure-release ball valve automatically. Trunnion-style PVC check valves are pressure-activated devices that shut off when the pressure exceeds a predetermined threshold. They are employed in chemical cooling, water purification, and processing procedures. Contrary to typical PVC valves, check valves lack a stem and a handle and have a straightforward design.
Flanged PVC Ball Valve
Flanged PVC ball valves are special because of their flange connection method. Because they are often full bore, they have a high flow rate. Two, three, or four ports are available, and a flanged PVC Ball Valve is lightweight and simple to install. Depending on the application’s pressure, the flange’s thickness changes. Ball valves with PVC flanges are attached with bolts or glue and a gasket.
Floating PVC Ball Valve
A full port PVC Ball Valve has an aperture the same size as the pipeline’s diameter. When the valve is open, the media flow is unfettered, and there is no pressure loss since the hole in the valve is the same size as the pipeline. Full port PVC ball valves are recovery valves for systems that demand a high flow coefficient and a low-pressure drop.
Manual Operated Valves
Manually controlled PVC ball valves are the simplest and feature the most straightforward designs. Adjusting the handle so that it is parallel to the pipe allows a two-way PVC ball valve to be opened. The handle must be positioned such that it is parallel to the pipe to close the valve. The handle must be rotated a quarter turn in either direction to open or close the valve. Knowing the boring design is crucial when manually operating a three-way PVC ball valve since ports might be positioned differently. Depending on the valve’s bore design, a quarter-turn of the handle can alter the flow direction.
Slip PVC Ball Valve
Slip fittings are present on the inlet and outlet of PVC ball valves. They are simple to slip onto a pipeline and can be installed on pipes up to two inches in diameter. PVC ball valves made of slip are attached with solvent cement and primer.
Standard Port Valve
The design of a full port PVC valve and a normal port PVC Ball Valve are identical. The size of the aperture in the ball distinguishes the two. Standard PVC ball valves have openings that are slightly narrower than the diameter of the pipeline, as opposed to full port PVC ball valves, which cause a larger pressure drop and a slower media flow rate.
Threaded PVC Ball Valves
Internal or exterior threads on threaded PVC ball valves help with inlet and output connections. The most popular and diverse PVC ball valves are threaded ones, which come in several variations based on the application and medium.
Three-Way PVC Ball Valve
A PVC ball valve typically has a two-way design with an inlet and an exit. As seen in the figure below, three-way multiport PVC valves are available with either T-shaped or L-shaped ports. The L or T shape PVC ball valve can help mix, distribute, and divert media flow. Turning the valve a quarter turn will allow you to place one of the two standard port designs.
Trunnion PVC Ball Valves
PVC ball valves with trunnions differ from other varieties of PVC ball valves. They are firmly held in place by a pin at the bottom of the ball. To keep the ball in place under pressure, the ball is segmented and supported by two shafts at opposite ends. The two supports keep the ball from shifting or blowing out when the ball is under pressure.
V Port PVC Ball Valves
V port Ball valves made of PVC feature a V-shaped aperture or seat. The bottom or tip of the V is the first section of the opening to receive the flow when the valve is opened. The V-shaped arrangement, which improves flow management, calls for using the highest grade of PVC with notches that might be 30°, 60°, or 90°. Because of the high pressure and increased flow rate experienced by V-shaped PVC ball valves, the base material is made of exceptionally strong PVC.
Vented Ball Valves
With a tiny hole drilled into the ball, PVC-vented ball valves relieve pressure in the medium. The opening allows trapped liquid and gas to escape, protecting the ball from injury. Depending on where the vent is positioned on the valve, they can be vented either internally or externally and face either upstream or downstream. Venting is used to discharge accumulated pressure that is trapped inside the valve when it is closed.
The many PVC Ball Valve varieties are made to serve particular purposes. The number of ports, varieties of seats, body assembly, ball access, and the bore size are used to categorize them. Find the best PVC Ball Valve online only at Petron Thermoplast. Visit now!
