Description
The Zurn Wilkins P1000AXL-125C is a 3/4" pressure relief valve for water heater / storage tank, factory set at 125 psi.
The P1000AXL Pressure Relief Valve is utilized on water heating storage vessels for protection against over-temperature or excessive pressure (not for steam service). Primarily used on storage tanks, P1000AXL materials include cast brass or bronze for the main valve body, quality stainless steel 300 series internals, stainless steel springs, and FDA approved, epoxy-coated copper tube probes. Multiple pressure relief settings and inlet/outlet connection options provide easy, ultra versatile installation capabilities, and the P1000AXL assembly shall be used where pressure only relief is required.
Features
- Eliminates risk of over-pressure of storage tanks
- Epoxy-coating adds extra protection
- Pressure relief valve settings of 30, 75, 125, and 150 psi offer versatility
- CSA Compliance to ANSI Z21.22/CSA 4.4
- Certified to ASME Section IV by National Board
Common Questions
- What pressure is this valve set to?
- It is factory set to relieve at 125 psi. The setting is fixed and is not field-adjustable.
- Will it fit my water heater - what BTU input does it cover?
- This valve is rated for 200,000 BTU/hr on the ANSI Z21.22/CSA 4.4 basis. Code requires the relief valve's discharge capacity to equal or exceed the input of the appliance it protects, so compare it against the input rating on the heater's data plate.
- Can I use this on potable water?
- Yes - it is certified lead-free under NSF/ANSI 372, which plumbing codes require for any device in a drinking-water line.
