What is Double Union Ball Valve 63mm RAKtherm PPRc ?

 

The Double Union Ball Valve 63mm RAKtherm PPRc PN 25 is designed to control the flow of hot and cold water in piping systems. This durable valve, made from polypropylene random copolymer, effectively isolates or shuts off water flow in HVAC circuits and general pressurized water supply networks.

RAKtherm’s PP-R system is specifically crafted for delivering pressurized hot and cold water. The company manufactures its products under the RAKtherm/Tahweel group in the UAE, ensuring quality and reliability.

What it is

This valve features a 63 mm PP-R body with a double-union design, allowing for easy removal and servicing without the need to cut the pipeline. In its catalog, RAKtherm includes a “Ball Valve” category within its PP-R product range. The system is engineered to handle water and various fluids in residential, commercial, and industrial installations.

Main specification

• Size: 63 mm.offerswala+1

• Pressure rating: PN 25.offerswala+1

• Material family: PP-R / PPRc.

• Application: hot and cold water, potable water, HVAC chilled/hot water loops, and general pressurized water networks.

• Service concept: suitable for pressurized warm or cold water systems and heating installations.

RAKtherm’s technical documentation highlights that its PP-R systems are suitable for potable water installations, chilled water systems, and heating networks. The material can withstand continuous temperatures of up to 70 °C, with the ability to handle short-term peaks reaching 100 °C.

How it works

The ball inside the valve enables quick quarter-turn shutoff, making it primarily suitable for on/off isolation rather than throttling. The double-union ends facilitate easier maintenance, allowing for the removal of the valve body while keeping the piping intact.This feature proves particularly advantageous in HVAC plant rooms, risers, manifolds, and equipment isolation points.

Installation notes

Ensuring proper welding, alignment, and installation practices is crucial for creating reliable joints.

Practical installation points:

• Use the correct PP-R socket welding temperature and heating time for 63 mm fittings.

• Keep the valve body aligned to avoid stress on the unions.

• Do not over-tighten union nuts; tighten enough to seal, not to distort the seats.

• Provide support on both sides so the valve does not carry pipe weight.

• Check the arrow or flow direction only if the valve model is directional; many union ball valves are effectively bi-directional for isolation, but verify the actual product marking.

Where it is used

This valve is typically used in:

• Domestic hot and cold water mains.

• HVAC chilled water isolation lines.

• Boiler and water-heater connections.

• Pump discharge or suction isolation, where compatible with the system design.

• Distribution manifolds and risers in residential, commercial, and industrial buildings.

Why PN 25 matters

 In RAKtherm’s hot-water service-life tables, PN 25 gives the highest allowable working pressure among the listed PP-R pressure classes, especially at lower temperatures.

For a 63 mm PP-R valve in a water-supply or HVAC system, PN 25 is a good choice when you want extra pressure margin, better suitability for pumping systems, and more robust operation in demanding plumbing layouts.

Important caution

“Imported from UAE” refers to the origin or sourcing route, but the actual performance still depends on the exact RAKtherm model, batch quality, and the installer’s welding skill. Also, a PP-R ball valve is usually best for isolation; if you need precise balancing or modulating control in HVAC, a control valve is often more appropriate than a standard ball valve.buildings.honeywell+1
