Aqua-Plus PP-R ball valve - weldable version

Full bore ✓ Sizes from DN20 to DN40 ✓ EPDM gaskets ✓

The white Aqua-Plus PP-R ball valve is used to open and close the water circuit and is firmly integrated into the pipe system by welding it to PP-R pipes of identical diameter. We offer the ball valve in the four sizes DN20, DN25, DN32 and Dn40 at favourable prices to match the PP-R pipes available from us. The inner diameter as well as the diameter of the bore in the ball corresponds to the inner diameter of the pipe. This design is also known as a full bore ball valve, where the flow remains unimpeded when fully open. The large, white lever handle can be marked with the supplied colour markings in red and blue for hot and cold water pipes.

In contrast to the ball valve with screw connection, the lower-priced version is connected directly to the pipe ends by welding and thus ensures a permanent, waterproof and pressure-tight connection between the pipes and the ball valve, which is long-lasting and maintenance-free if the welded connection is carried out carefully.

Features of the PP-R ball valve with handle lever

With the exception of the seals, the Aqua-Plus PP-R ball valve is made of white polypropylene random copolymer - PP-R for short. This plastic is characterised by a whole range of positive properties, the most important of which is its approval for drinking water supply in accordance with DVGW and SKZ. With a temperature resistance of -10°C to +95°C, the Aqua-Plus system can be used without hesitation for cold and hot water pipes, regardless of whether they are drinking water pipes, heating pipes, pipes for garden irrigation or for supply and discharge pipes of solar thermal systems. Thanks to the very good chemical resistance, the pipes, as well as the solidly manufactured ball valve with seals made of EPDM, can also be used for transporting chemicals in the pharmaceutical and chemical industries.

The ball valve for fixed connection by welded joints is a pre-assembled fitting in which a ball inside causes the water circuit to open and close by turning the lever handle. The opening of the ball corresponds to the inner diameter of the matching pipe size, so that liquids can flow through without flow losses when the ball valve is fully open. For absolute tightness, the ball is enclosed on both sides with a high-quality seal made of ethylene-propylene-diene rubber.

In the ball valve, a brass ball rotates inside, and the bore opens the water circuit when the lever handle is turned in the direction of flow. If the handle is turned 90 degrees to the pipe, the opening of the ball also turns so far that no more water can flow through the ball valve. Due to the so-called dead space-free design, in which there are no cavities inside the ball valve, deposits from calciferous water or impurities inside the liquids cannot accumulate in such cavities when the circuit is opened or closed. This has a positive effect on the already very long service life of the ball valve and prevents leaks that could otherwise occur if deposits impair the complete closing of the mechanism.

Processing of the PP-R ball valve with welded connection

The ball valve made of polypropylene random copolymer has a welding socket on both sides for pipe reception. The diameter of the two pipes is identical and depends on the selected size of the ball valve. Welding is very simple and quick. For this purpose, a socket welder with suitable inserts is required, in which the pipe is inserted or the pipe socket of the valve is put on. This should be done at the same time so that the heating time is maintained for both elements. Afterwards, the pipe must be inserted straight and without twisting it into the holder of the ball valve until the required insertion depth is reached. Note the positioning of the handle lever beforehand so that it is accessible and can be operated after the pipe system has been installed. As soon as the welded joint has cooled down sufficiently, the opposite side can be welded using the same procedure.

How long the pipe and the socket have to be heated depends on the outer pipe diameter. The smaller the outside diameter, the shorter the time required for heating with the welding machine. The same applies to the cooling phase and the insertion depth, which is 14mm for the smallest diameter and increases by 2mm with increasing pipe size, so that the insertion depth for a DN40 pipe is 20mm. To make it clear and simple, we have created a separate installation data sheet for each pipe diameter, in which we have summarised all the data that is relevant for welding the plastic. In addition, these data sheets contain further information on assembly, assembly distances, as well as expansion for hot water pipes.

NOTE: The end of the pipe cannot be inserted into the fitting without sufficient softening, as for technical reasons, the pipe socket of the fitting is approx. 0.5 mm smaller than the outer diameter of the pipe.
