What is Stop globe valve 40mm RAKtherm PPRc ?
The 40 mm RAKtherm PPRc Stop Globe Valve (Gate Valve) PN 25 is a manually operated shut-off valve designed for PPR (Polypropylene Random Copolymer) piping systems. Manufactured in the United Arab Emirates (UAE), it is used to start, stop, and isolate water flow in hot and cold water distribution systems and HVAC applications. The valve is joined to PPR pipes using socket fusion welding, creating a permanent, leak-free connection. RAKtherm offers these valves in multiple sizes, including 40 mm, for medium-pressure water systems.

Applications
The 40 mm Stop Globe Valve is suitable for:
- Hot water supply systems
- Cold water distribution
- HVAC chilled water systems
- Central heating networks
- Commercial buildings
- Residential plumbing
- Hospitals
- Hotels
- Schools
- Industrial water distribution
- Mechanical equipment isolation
- Pump discharge and suction isolation
- Water treatment plants
Working Principle
The valve operates using a handwheel connected to a threaded stem.
- Turning the handwheel counter-clockwise raises the internal gate/disc and allows water to flow.
- Turning it clockwise lowers the gate/disc onto the valve seat, stopping water flow.
- It is intended primarily as an isolation valve rather than for continuous flow throttling.
Installation Procedure
- Cut the 40 mm PPR pipe square using a PPR pipe cutter.
- Clean the pipe ends and valve sockets.
- Heat both the pipe and valve socket using a PPR fusion machine (typically around 260°C).
- Insert the pipe into the valve socket without twisting.
- Hold the joint until the plastic cools naturally.
- Ensure the valve is aligned correctly with the intended flow direction.
- Support the pipeline to avoid excessive stress on the valve.
- Perform a hydrostatic pressure test before putting the system into service.
Usage
This valve is commonly installed:
- Before water heaters
- On pump inlet and outlet lines
- On HVAC branch lines
- At floor distribution manifolds
- On risers in multi-storey buildings
- Before storage tanks
- For equipment isolation during maintenance
- At plumbing branch connections
Advantages
- Reliable shut-off performance.
- Low maintenance requirements.
- Corrosion-free construction.
- Hygienic for drinking water.
- Long operational life.
- Strong fusion joints eliminate threaded leaks.
- Suitable for concealed or exposed installations.
- Compatible with complete RAKtherm PPR piping systems.
Suitable Systems
- Domestic hot and cold water
- HVAC chilled water
- Heating water circulation
- Potable water networks
- Commercial plumbing
- Industrial process water
- Building services engineering
- Mechanical piping systems
Good Installation Practices
- Use only a calibrated PPR socket fusion welding machine.
- Avoid overheating during fusion.
- Keep the valve fully open during welding to reduce heat transfer to internal seals.
- Do not use the handwheel to tighten pipe connections.
- Install pipe supports near the valve to minimize mechanical stress.
- Flush the piping system before commissioning.
- Pressure-test the installation according to applicable plumbing standards.
The RAKtherm PPRc Stop Globe Valve (Gate Valve) 40 mm PN 25 is a durable and dependable isolation valve for hot and cold water plumbing, HVAC chilled water, and mechanical water supply systems. Its corrosion-resistant PPR construction, fusion-welded joints, and PN 25 pressure rating make it well suited for residential, commercial, and industrial installations requiring long-term reliability.
