Poly-Water® Ball Valve, Polyethylene Water Ball Valve
Poly-Water® polyethylene water ball valves are valves designed for controlling the flow of water in plumbing systems. They are specifically made using polyethylene, a durable and versatile thermoplastic material.
These valves are commonly used in residential, commercial, and industrial applications due to their various advantages such as corrosion resistance, chemical resistance, lightweight, cost-effective, durability and ease of operation.
Before making your final determination on valve suitability for your specific application and compatibility with the intended system, please consult with our experienced sales team to ensure the appropriate valve material is chosen for your particular water system.
Product Features & Benefits
- POLYETHYLENE: Corrosion-free due to high-grade polymeric materials. There are no metal internal parts.
- RUGGED AND RELIABLE: Polyvalve Poly-Water® valves are the strongest part of a polyethylene piping system.
- FUSED BODY SHELL: The fused body shell removes leak paths to the atmosphere.
- ENHANCED SEALING PERFORMACE: Multiple elastomeric stem seals provide improved sealing efficiency compared to a single seal. The additional seals create multiple barriers, reducing the chances of leakage and ensuring a tighter seal.
- DUAL ELASTOMERIC SEATS: The drop-tight shutoff from dual elastomeric seats creates a leak-tight seal.
- NSF CERTIFIED: Poly-Water® valves are NSF certified (National Sanitation Foundation) for use in potable water systems.
- SMOOTH BORE: The smooth bore gives excellent flow characteristics in both full and reduced port designs.
- BROAD TRIM SELECTION: A variety of trim is availabe depending on specific applications.
- END CONFIGURATIONS: Flanged end configurations are available.
Why use Poly-Water® Valves?
Polyvalve is the first company to manufacture polyethylene (PE) valves for natural gas distribution.
Millions of Polyvalve Poly-Water® valves have been sold since 1976 and are in use throughout the world. Here’s why
- Rugged and reliable Polyvalve Poly-Water® valves are the strongest part of a polyethylene piping system.
- Drop-tight shutoff from dual elastomeric seats
- Fused body shell removes leak paths to atmosphere
- Multiple elastomeric stem seals
- No metal internal parts
- High-grade polymeric materials eliminate corrosion
- Smooth full bore gives excellent flow characteristics in both full and standard port designs
- Wide variety of trim for your specific application
- Flanged end configuration available
- Poly-Water valves are NSF certified for use in potable water systems
All Metal System (Welded or Bolted)
- Subject to external corrosion, internal scaling and damage from ground movement
- Too-rigid pipe can rupture during frost heave or heavy pressure in hot weather
- 30% of all system water is lost to leaks
Polyethylene Pipe-to-Metal Valve Installation
- Subject to the inherent weakness of combining incompatible materials
- Vulnerable to ground movement during extremes of cold or heat
- 30% of all systems water is lost to leaks
All-Polyethylene Systems
- Intrinsically safe—the valve is an integral part of the pipe
- No leak points
- No chance of corrosion
- Flexible polyethylene systems are less susceptible to ground movement
