Whether you're managing hot or cold water lines, this valve's S-type lifting design ensures smooth, reliable operation every time.

Why Choose This PPR Globe Valve?

• High Flow Design: S-type straight-through passage minimizes flow restriction for maximum water throughput.
• Hot Melt PP-R Material: Made from premium PP-R (Polypropylene Random Copolymer) for excellent corrosion resistance, durability, and a leak-free seal after heat fusion joining.
• Iron Handwheel: Solid iron handwheel provides a firm, comfortable grip for easy manual operation — open or close in seconds.
• Lifting Gate Mechanism: The precision-machined lifting spindle design ensures a tight shutoff with minimal wear over thousands of cycles.
• Quick-Release Union Connection: Union-type fittings allow for fast installation and easy removal for maintenance without cutting the pipe.
• Rated Up to 850 kPa: Engineered for safe operation at pressures below 850 kPa, suitable for most residential and light commercial plumbing applications.
• Versatile Use: Ideal for water supply lines, heating systems, irrigation setups, and general plumbing pipe runs.

Installation Tips

This valve uses a hot melt (heat fusion) joining method — simply heat both the pipe and fitting socket to the manufacturer-recommended temperature, then push together for a permanent, leak-proof bond. The union design also means you can disconnect the valve without disturbing the fused pipe joints, making future servicing straightforward. Always ensure the pressure in your system does not exceed 850 kPa before installation.

Frequently Asked Questions

Q: What is a PPR S-Type Globe Valve and where is it used?

A: A PPR S-Type Globe Valve is a flow-control fitting made from PP-R (Polypropylene Random Copolymer) plastic with an S-shaped internal passage that allows high flow rates. It is commonly used in residential and commercial water supply pipes, underfloor heating systems, and irrigation lines to manually start, stop, or regulate water flow.

Q: What does "hot melt" connection mean?

A: Hot melt (or heat fusion) connection means the valve and pipe are joined by briefly heating both surfaces with a special welding tool, then pressing them together. As they cool, they fuse into a single, leak-proof joint — no glue, threading, or clamps required.

Q: What is the maximum pressure this valve can handle?

A: This PPR S-Type Globe Valve is rated for operating pressures below 850 kPa (approximately 123 PSI). It is suitable for standard residential and light commercial plumbing where pressures typically fall well within this range.

Q: Why does the valve have a union-type quick-release fitting?

A: The union-type design allows you to disconnect the valve from the pipe system without cutting or removing the fused pipe joints. This makes maintenance, replacement, or inspection of the valve quick and easy — simply unscrew the union nuts to remove the valve body.
