Prevost PPS Parallel Female Thread Valve

The Prevost PPS Parallel Female Thread Valve is a high-performance isolation valve designed to act as a bridge between threaded industrial equipment and the modular Prevost Piping System (PPS). This valve combines a standard parallel female thread (BSPP/G-thread) on one side with a direct push-to-connect pipe fitting on the other.

This “hybrid” design eliminates the need for separate adapters, allowing you to connect compressors, tanks, or dryers directly to your aluminum network while providing immediate manual shut-off control for maintenance and safety.

Key Features & Benefits

• Integrated Connection & Control: Functions simultaneously as a pipe adapter and a shut-off valve. This streamlined design reduces installation time and minimizes the number of potential leak points compared to screwing a standard valve into a separate adapter.
• Full-Bore Efficiency: Features a “full port” ball design internally. When open, the bore matches the pipe diameter perfectly, ensuring zero restriction and maximum airflow to downstream equipment.
• Quarter-Turn Operation: The ergonomic handle provides quick, low-torque operation. A simple 90° turn completely isolates the line, offering immediate visual confirmation of the valve status (handle parallel to pipe = Open; handle perpendicular = Closed).
• Secure Thread Sealing: The parallel female threads are precision-machined to ensure a tight, flush seal against male-threaded equipment or nipples, supported by a flat face for gasket sealing where applicable.
• Heavy-Duty Durability: The body is constructed from high-grade materials (typically nickel-plated brass or aluminum alloy depending on size) to resist corrosion and withstand the mechanical stress of heavy industrial environments.

Technical Specifications

• Part Series: PPS1 V (Valve Series)
• Connection Type:
  • Side A: Parallel Female Thread (BSPP / G-Thread)
  • Side B: PPS Connection for Aluminum Pipe
• Mechanism: Full-Bore Ball Valve
• Material: Nickel-Plated Brass or Aluminum Alloy (Body) / Stainless Steel (Grip Ring)
• Operating Pressure: Up to 232 PSI (16 bar)
• Operating Temperature: -4°F to +176°F (-20°C to +80°C)
• Vacuum Compatible: Yes (Up to 29″ Hg)

Ideal Applications

• Compressor Discharge: Screwing directly onto the male outlet of a compressor or receiver tank to connect it to the main aluminum header.
• Zone Isolation: Connecting threaded FRL (Filter, Regulator, Lubricator) units to the piping system with the ability to shut off air for filter changes.
• Machinery Inlet: Providing a main shut-off point at the air inlet of heavy machinery that utilizes a male threaded connection.
