What is Stop Valve?
A Stop valve is a linear motion valve that uses a cartridge moving perpendicularly to the seat to start, stop, or regulate fluid flow. It features a forced-seal design where the closure member is pressed against the seat by the stem to ensure tight shut-off.
The features of a PPR Stop Valve:
- High Temperature Resistance: Suitable for both cold and hot water (up to 95°C).
- Heat Fusion Connection: Joins with pipes by melting, creating a leak-proof seal.
- Hygienic: Non-toxic and safe for drinking water.
- Corrosion Resistant: Will not rust or degrade when in contact with chemicals.
- Low Heat Loss: Good insulation keeps hot water hot.
- Smooth Flow: Smooth inner wall prevents scaling and blockage.
- Installation: Requires a special welding machine to install.
Work Principle For Stop Valve:
A stop valve works by moving a cartridge to block or open a pipe.
- To Stop Flow: You turn the handle to push the cartridge down onto the seat, sealing it shut.
- To Start Flow: You turn the handle to pull the cartridge up away from the seat, letting fluid pass through.
Advantages of PPR Stop Valves Over PVC Stop Valves
| Feature | PPR Stop Valve | PVC Stop Valve |
| Max Temperature | Up to 95°C (suitable for hot water) | Up to 60°C (cold water only) |
| Joining Method | Heat Fusion (creates permanent, leak-proof joint) | Solvent Cement (chemical bond) |
| Application | Hot & Cold water, Heating, HVAC | Cold water, Drainage, Chemical drainage |
| Hygiene | Non-toxic, high purity for drinking water | Good, but may have plasticizers |
| UV Resistance | Moderate (requires protection/UV-stabilized grades for prolonged exposure) | Poor (can become brittle in direct sunlight) |
Applications
- Boilers and Auxiliaries: Used in critical parts such as boiler blowdown, feedwater pipelines, and steam outlets, requiring reliable sealing and quick opening/closing under high temperature and pressure.
- Petrochemical Pipelines: Used for conveying pressurized oil products, chemical raw materials, or process gases.
- High-Rise Building Fire Protection or Water Supply: Serves as control valves for zone-specific water supply or fire protection pipelines in high-rise buildings.
- Thermal Power Plants: Used for isolation and throttling of various medium-pressure water and steam pipelines.
