- Valves are cleaned for medical service per CGA guidelines.
- Order gauges (sold separately) for zone valve application.
- When installing sensors inside of zone valve box, order one remote sensor kit per gas
- Meets or exceeds NFPA code for Medical Gas Pipeline System Components.
- Made in the USA
Zone Valve Box Assembly
Valves shall be full port, double seal, ball-type with three
piece bronze/brass body and a chrome plated brass ball.
Valves shall be designed for a maximum working pressure
of 600 psig WOG or vacuum service to 29″ Hg. Valve body
shall have reinforced PTFE ball seat and reinforced PTFE
stem seals, and stem shall be blowout proof. All valve
materials shall be compatible with USP oxygen, nitrous
oxide, medical air, carbon dioxide, helium, nitrogen, argon
and mixtures thereof.
A 1/4 turn of the handle shall be required to operate the
valve from OPEN to CLOSED position. The valve shall be
securely attached to the box and provided with type K
copper tube extensions for making connection to system
piping outside the box. All valves shall be serviceable in the
line, supplied clean and prepared for oxygen service.
All valve assemblies have a total of three 1/8″ NPT ports with
pipe plugs. One port is used as a provision for connection
of a gauge and shall be located on the terminal outlet side
of the valve to register pipeline pressure or vacuum. The
second port is used as a provision for a DISS connection of
a gas sensor. The third port is used for purging during the
brazing process and is located upstream of the valve.
The zone valve and box assembly shall meet all requirements
of NFPA 99, CAN/CSA Z7396.1-09 and AS2896-2011.
The valves conform to MSS SP-110. Type K copper tube
extensions conform to ASTM B88, UNS No. C12200, and
H58 temper. The gauges shall conform to ANSI B40.1.
Zone Box Design
The zone valve box shall be constructed of 18-gauge steel
with white epoxy finish. The 1/2” through 2” valves require
a rough wall opening of 13 5/8″ wide x 4″ deep. The 2-1/2”
and 3” valves require a rough wall opening of 15-7/8” wide
x 10” high x 6-11/16” deep. For ease of installation, two
18-gauge galvanized steel mounting brackets, adjustable
from 3/8″ thick to 1.5″ drywall, are provided.
The zone valve box assembly shall have a sliding, opaque
door with pull ring and clear gauge window. The door shall
be capable of sliding to the right to facilitate installation
requirements. In an emergency, the door shall SNAP OUT
by pulling the pull ring forward without exposing sharp
edges.
The zone valve box shall be provided with an advanced
polymer (ABS) trim frame designed for high impact
resistance and capable of adjusting to variations in wall
thickness up to 1″ below flush. The design allows for the
configuration of up to 7 valves within the rough-in box
assembly. Gas flow should be from left to right. Nylon 6/6
Insulated grommets allow for ease of valve replacement
and reorientation within the rough-in box. The Zone Valve
Box door is treated with Biomaster (see table on pg.4 for
details). The zone valve box assembly shall be supplied with
color-coded gas identification labels. The gas identification
labels are also available online for printing. The assembly
door shall have a label that reads:
-CAUTION- CLOSE VALVES ONLY IN EMERGENCY
