Supply & Demand

The main body of the valve is made of PPR material, and both ends have heat-melt socket connections that are compatible with PPR water pipes; the internal valve core and valve stem adopt a brass sealing structure, with a handwheel switch on the top, and are formed by one-piece injection molding. There are standard specifications such as 20/25/32 diameters.

The entire product is made through a single injection molding process of food-grade PPR. There are two heat-melt socket connections of the same specification, forming a 90-degree right angle, without metal threads. There is also a 45-degree elbow of the same series.

通体纯 PPR 原料一体注塑成型，三个端口规格一致，全部为热熔承插口，无金属螺纹。

One end is a PPR plastic socket (heat fusion butt joint PPR pipe), with a 90° angle; the other end has an embedded thickened brass internal thread, which is injection-molded as one piece; the mainstream socket specifications for home decoration are 1/2" (4/4) and 3/4" (6/4).

The two connectors are pure PPR interfaces (heat fusion butt PPR pipes), with internal brass threads in the middle branch, and are formed by one-piece injection molding. There are also three-way connectors with equal diameters, and the commonly used sizes for home decoration are 4-inch and 6-inch internal threads.

PPR direct connection, also known as PPR direct, both ends are PPR plastic sockets, using hot melt welding. It is used for straight connection between two sections of PPR pipes of the same diameter. It is the most basic pipe fitting for water supply systems.

The PPR external thread connector has one end as a PPR plastic socket (for hot-melt connection of PPR pipes), and the other end is a metal external thread. It is specifically designed to achieve the connection between PPR plastic pipes and metal fittings with internal threads or metal hoses, and is a necessary conversion pipe fitting for waterway installation.

UPVC Transparent Cross (Clear PVC-U Cross), made through a single injection molding process of high transparency, non-stretched hard polyvinyl chloride, featuring a four-way socket connection structure, enabling the diversion and confluence of four pipelines; the entire body is highly transparent, allowing for direct observation of internal fluids, sediment, bubbles, and crystals. It is a specialized pipe fitting for visual monitoring of pipelines and can be bonded with transparent UPVC pipes, transparent elbows, and three-way fittings using compatible adhesives.

UPVC transparent union ball valve (Clear PVC-U True Union Ball Valve), the valve body, union core and ball core are injection-molded from high transparency non-stretched hard polyvinyl chloride. The two ends are separated and fitted with a split sleeve with a locking structure, and are equipped with a manual switch handle. The entire body is transparent, allowing for direct observation of the internal medium, impurities and liquid level. The pipe connection is achieved by the 90° rotation of the spherical valve core. It is a visual anti-corrosion control valve that can be fully matched with transparent UPVC pipes and transparent pipe fittings for bonding and installation.

UPVC transparent flange (Clear PVC-U Flange), made by one-piece injection molding of high transparency, non-stretched hard polyvinyl chloride, is divided into two structures: transparent sleeve flange (separate flange) and transparent one-piece flange; it consists of transparent socket core, transparent flange disc, and EPDM sealing gasket, and is used for detachable connection between transparent UPVC pipelines and valves, pumps, and equipment. The entire pipeline is transparent, allowing for direct observation of medium flow, leakage, and crystalline impurities at the interface, making it a special pipe fitting for visualized anti-corrosion pipelines.
