Apollo Pressure Reducing Valves — 36 Series

Apollo 36 Series pressure reducing valves (PRVs) are factory-tested, ASSE 1003 certified devices designed to reduce incoming water pressure to a safe, preset downstream level. Used in commercial plumbing, residential buildings, and institutional facilities, Apollo PRVs protect downstream piping, fixtures, and equipment from high-pressure damage. PVFPro stocks the full 36 Series line including union FNPT, press-fit, solder, and the 36ELF lead-free direct-acting model.

Applications

• Commercial buildings — point-of-entry pressure reduction for multi-story and high-pressure service areas
• Institutional facilities — hospitals, schools, government buildings with strict pressure requirements
• Residential buildings — protecting plumbing fixtures and appliances from high municipal pressure
• HVAC systems — reducing supply pressure to boilers, heat exchangers, and hydronic circuits
• Irrigation systems — protecting drip and spray systems from pressure spikes
• Industrial processes — controlling supply pressure to equipment with specific pressure requirements

Frequently Asked Questions

What pressure does the 36 Series reduce to?

Apollo 36 Series PRVs are available in multiple factory-set pressure ranges. The adjustable models allow field adjustment within the valve's rated range. Standard setpoints range from approximately 25–75 psi depending on the model selected.

Do I need a PRV if my incoming pressure is above 80 psi?

Most plumbing codes require a PRV when service pressure exceeds 80 psi. High pressure damages plumbing fixtures, water heaters, and appliances and increases leak risk. A PRV protects the entire downstream system.

Are service/repair kits available?

Yes. Apollo 36 Series repair kits are available in our Apollo Service Kits collection to rebuild the valve and restore performance without full replacement.
