[New Proposal] Installation of Shut-off Valves and Fire Hydrants - Suppon MPX

[New Proposal] Installation of Shut-off Valves and Fire Hydrants - Suppon MPX

Realization of flange-less seismic-resistant piping! Installation of shut-off valves and fire hydrants on high-density polyethylene piping can be done using mechanical methods!!

The Suppon MPX soft seal valve with base is an integrated soft seal partition valve equipped with a mechanical type receiving port. The Suppon MPX MP-TF base for fire hydrants makes it easy to install fire hydrants and air valves, and the base improves stability. Due to the lack of flanges, no joining materials (gaskets, bolts, nuts) are required, leading to cost reduction and a decrease in the risk of leaks by reducing connection points. Thanks to the mechanical receiving port structure, there is no need for specialized fusion machines, clamps, generators, or other equipment, allowing for immediate water flow after installation regardless of site conditions such as water locations or weather, thus shortening construction time. The diameter ranges from 50mm to 200mm, and there is a rich lineup that allows for connections with different types of pipes. There is also a lineup of Suppon MPX MP-BF bases for fire hydrants designed for the ends of pipelines.

Repair fittings and repair work, closer universal joint, CRS type.

Repair fittings and repair work, closer universal joint, CRS type.

It is ideal for earthquake resistance and ground subsidence measures.

When an earthquake or ground subsidence occurs, displacement occurs in the piping. If the displacement progresses, there is a possibility that the piping will be damaged, leading to leaks. To absorb the displacement, it is necessary to install flexible pipes. In such cases, it is necessary to cut and remove part of the piping and connect the flexible pipe through welding, which requires a lot of time. This product does not require welding, allowing for quick installation. It absorbs expansion, eccentricity, and twisting, and provides permanent water-stopping performance.

PVC pipe compatible Excel software partition valve

PVC pipe compatible Excel software partition valve

A soft-seal partition valve that can be directly inserted into hard PVC pipes or steel pipes for connection.

The installation is simple, requiring only the insertion of the pipe and tightening of the nut. The claw ring firmly holds the outer circumference of the pipe to prevent disconnection. 【Features】 - After inserting the pipe into the valve, simply remove the spacer and tighten the nut, which shortens the installation time. - Since flange joints are not required, traditional PVC pipe fittings (such as short pipes and flanges) are also unnecessary, reducing total costs. - The claw ring and rubber ring sufficiently meet the disconnection prevention performance standards of the Japan Water Works Association (JWWA K 131). - It can also be used with steel pipes, making it suitable for temporary piping. - It is compatible with shallow burial for all nominal diameters. - Applicable pipe types: rigid polyvinyl chloride pipes (excluding VU pipes with a nominal diameter of 50mm), steel pipes, and polyethylene two-layer pipes for water supply (Type 1) (only for nominal diameter of 50mm).

K-shaped insertion Excel software partition valve

K-shaped insertion Excel software partition valve

JWWA B 120 water supply soft seal partition valve integrated with K-shaped ductile iron irregular pipe's receiving and inserting ends, contributing to improved workability.

JWWA B 120 is a product that integrates a soft-seal partition valve for water supply with K-shaped ductile iron irregular pipes at the receiving and insertion ends, unifying the joint direction of the pipeline and contributing to improved workability. 【Features】 〇 Since the entire pipeline can be unified with K-shaped joints, there are fewer restrictions on the installation position of the valve compared to conventional flange types. 〇 Excellent water tightness is achieved by a method that tightens the rubber ring with a pressing ring, strongly adhering the inner surface of the receiving end and the outer surface of the insertion end. 〇 It can be installed in a lighter and more compact manner than the combination of conventional flange types (K-shaped short pipe type 1 + flange type soft-seal partition valve + K-shaped short pipe type 2), reducing construction costs. 〇 The height dimension for the short (shallow burial) type can accommodate up to a nominal diameter of 200mm with a soil cover of 600mm.
