A double union ball valve has, as implied, two unions on it – one on either side. The unions enable the valve to be unscrewed and removed from the pipeline, where it can be serviced or checked to see whether it's blocked, and then easily put back in the pipeline where the unions can get screwed back on. This means that to get to your valve and service it, you won’t have to worry about cutting your pipe. It also means that returning your valve to your pipe system is a fast process and won’t keep your system down for long.

The main advantage of a double union ball valve is that it has a full-bore flow all the way through. This means there is nothing to catch any debris that might be coming down in the water or fluid. Therefore, it is highly unlikely to get blocked.

An alternative to a double union ball valve, which still has the same benefits of a full-bore flow, is a single union ball valve. However, a single union ball valve only has a union on one side of it. Due to this, a single union ball valve should be used at the end of a pipeline rather than in the middle of a system. If it was used in the middle of a pipe system and you had a problem with the valve, the only way to remove it would be to cut the pipe on one side and then unscrew the union. You would then be left with having to glue a fitting onto pipe. This means your system would be down for a lot longer. That's why we use double union ball valves in a system, and single union ball valves at the end of a system.

While ball valves have their advantages, they are not easy to control. There is only a quarter turn on the valve between fully open and fully closed, which means it is very hard to get a fine control of flow. They're great if you want a fully open flow, a fully closed flow, or perhaps somewhere around a half-flow. But if you want finer control than that, you are much better using a gate valve, which has around eight turns between fully open and fully closed. Gate valves enable you to get fine control on the valve and fine control of the flow.

All our ball valves are pressure tested to 10 bar pressure. They are also all wet tested at the factory before they come to us, so if you find a tiny bit of water or fluid in and around the valve when you take the unions off, that doesn't mean it's been used on someone else's system, it means it's been wet tested at the factory and is therefore in perfect working condition!

We understand that this is the biggest obstacle to sourcing the right PP clamp for your process and we have come up with three solutions.

The first solution is our unique PP Clamp Selector. If you know a number of the specific requirements for your Toggle Clamp you can enter those into the selector to narrow down your search. If you know the material required, the height under bar and the type, for example, you require a Stainless Steel lVertical PP Clamp with 50mm under bar, a bar length of 40mm which is base mounted, the selector will show only the clamps that match that criteria. You can check it out here, we think you will find it is the best Toggle Clamp Selector currently available.

The second solution is this site. We have worked particularly hard to ensure that you have the very best chance of finding the PP Clamp you need on this website by categorising our Toggle Clamps by type, mounting, finish and application. If you know one of these requirements you can browse all of the PP Clamp that we have available that fit that specification. If for example, you require a Toggle Clamp for a food manufacture application you can look at all of the Stainless Steel PP Clamp that we hold. If you require a Vertical Action PP Clamp you can browse only our Vertical Action PP Clamp. If you need to switch between the various types of clamps you can use our PP Clamp menu.

No matter how impossible or unique your PP Clamp challenge might appear to you now, with more than 50 years experience it is highly likely that our team have experienced something similar before and can quickly steer you in the right direction.

In the unlikely event that the PP Clamp you require really isn’t available in stock. We provide a Custom Toggle Clamp Design service to ensure you get exactly the PP Clamp that you need. You can check that out here.

Welcome to buy pvc ball valve!

1.The fluid resistance is small. The resistance coefficient is equal to that of the pipe of the same length.
2. Simple structure, small size, light weight.
3. Tight and reliable. Plastics are widely used in sealing materials of ball valves. They have good sealing performance and are also widely used in vacuum system.
4. Easy operation, quick opening and closing. From full opening to full closing, there only needs to be a 90 degrees rotation, which is easy for remote control.
5. Easy maintenance. Ball valves have simple structures, and the seals are usually active, which is convenient for removal and replacing.
6. When fully open or fully closed, the sealing of the ball and valve seat is isolated from the medium. When the medium flows through, there’ll be no corrosion of the sealing surface of the valve.
7. Wide range of application. The diameter can be as small as a few millimeters, or can be as large as a few meters. From high vacuum to high pressure, it can both be applied. When the ball rotates 90 degrees, spheres should be present at both the inlet and outlet, therefore cutting off the flow.

Certainly, the shut-off based applications are manufactured to handle an immense amount of pressure in terms of liquid flow within pipes. When it comes to purchasing 3- Way ball valves, it is mandatory for the person to check the kind of pressure that the specified valves are designed to handle as slightest negligence can cause leakage in pipes leading to devastating effects. In this regard, it would be great that the buyer happens to identify the exact size of the valve needed to fit into the pipeline structure.

Full Port Ball Valve
Full port or full bore ball valve is more expensive than other types. The oversized ball in the full port ball valve lowers the friction loss because the hole in this ball valve is the same size as the pipeline. Though the valve is larger, the flow is unrestricted in full port ball valve size.

Full bore ball valves are usually used for throttling applications in various systems with high flow coefficients and low pressure drops.

Standard Port Ball Valve
Compared to the full port, the standard port ball valve has a smaller port and ball. It’s less expensive but comes with a slightly restricted flow due to the pipe size. Though they are cheaper, they have higher pressure drops compared to other ball valve types. Standard port valves are great for systems with high flow coefficient, just lie full port valves.

V-Port Ball Valve
The V in the v-port ball valve represents either the shape of the seat or the shape of the ball. V ball valve enables you to control the opening and the closing better. The flow characteristic in this type is close to linear. The high velocities of the fluids used with such ball valves forced the designers to come up with generally more robust construction for them since these types of fluids quickly damage a standard valve.

Multi-Port Ball Valve
Multi-port ball valves have three or four ways with an L to T shaped hole in the middle. T valves can connect any pair of ports and the L valve can connect the center port to side ports. Inlet in a multi-port ball valve is usually orthogonal to the plane of the outlets. 4-way ball valves have 2 L-shaped ports in their ball known as X port.

Reduced-Port Ball Valve
Also known as RB, reduced-port ball valves or reduced bore the flow area is smaller than the pipe and the flow through the valve is one pipe size smaller than the valve’s pipe size. This type of ball valve creates a pressure drop in the pipeline.
