Axial Flow Pump Pressure Regulator - Model AF5

Increase efficiency and decrease maintenance time with the Model AF5 back pressure regulator, an updated component for the modern high-pressure water system. Made in the USA.

Features:

• Wear resistant contoured seat increases valve life
• Effective pulsation dampening
• Smooth and constant regulation independent of flow rate (less than 5% variation)
• Minimal parts for easy maintenance
• Optional ports for gauge and relief valve
• Pressure gauge and relief valve available as options

• Optimal Pressure Range: 100 to 3000 psi (requires spring change)
• Temperature: Up to 180°F
• Flow Rate: 5 gpm max
• Optimal Bypass: 5% of flow rate
• Weight: 2 lbs.

• Body: Electroless nickel plated brass
• Spring Retainer: Brass
• Fixed Seat: 416 Stainless steel
• Contoured Piston: 416 Stainless steel
• O-rings: Viton(R)
• Backup Ring: Teflon(R)
• Die Spring: Chrome silicon steel

Applications:
Back pressure regulator for self service car washes and automatic car wash systems. High pressure water sprayers. High pressure water systems which use fixed pump pressure.

Installation Instructions:
For optimal operation, bypass 5% of the total flow through the AF5. For example, for 5 gpm, bypass 0.38 gpm. Install the regulator either at the pump or downstream a short distance to maintain constant back pressure in the system. Install pressure gauge in the 1/4" port. Relief valve should be installed in the 3/8" port.
