Common Questions
- Is this UL/FM listed for fire service?
- No. Series 405 is not UL/FM listed — it is built for water distribution and irrigation service at 200 psi CWP. For a fire main shutoff, use the UL/FM listed 408-OSY-RW instead.
- Rising or non-rising stem?
- Non-rising stem (NRS). The stem turns but does not travel, so the valve fits tight spaces, buried service and pits. There is no visual open/closed indication — use an OS&Y valve where that is required.
- Is this a complete valve or just the replacement gate?
- Complete valve. The 405-RW 2 ships as a full assembly — body, bonnet, wedge, stem and handwheel. The Watts NRS-RW-GATE / OSY-RW-GATE items are gate assemblies only, sold to service an existing valve.
- What does "resilient wedge" mean?
- The wedge is a ductile-iron disc fully encapsulated in rubber, so it seals bubble-tight against the epoxy-coated body without a bronze seat ring and holds up against high differential pressure.
