Combo valve box with Alarm

Zone Valve Box Assembly

Valves are full port, double seal, ball-type with bronze/

brass body and chrome plated brass ball. Valves consist

of the following:

• Designed for a maximum working pressure of 150 PSI

• Valve body has reinforced PTFE ball seat and

reinforced

PTFE stem seals

• Valve stem is blowout proof

• All valve materials are compatible with oxygen,

nitrous oxide, medical air, carbon dioxide, helium,

nitrogen, argon and mixtures thereof

• A ¼ turn of the handle is required to operate the valve

from OPEN to CLOSED position

• Valves are securely attached to the box and provided

with copper tube extensions for making connection to

system piping outside the box

• 15 mm copper pipes for positive pressure gases and

22mm for vacuum

Zone Valve Box Design

• The zone valve box is constructed of 20-gauge, mild steel 

  with white epoxy powder coat finish

• Design allows for up to 6 valves within the assembly

• Suggested positive gas flow is from left to right & vacuum from right to left 

  Zone Box Door 

  Glass is provided on zone valve box assembly. In an 

  emergency, break the transparent acrylic sheet to close 

  the valves

• Acrylic sheet has a label that reads: - CAUTION -

CLOSE VALVES ONLY IN EMERGENCY

Digital Alarm Panel Configuration

• Digital Alarm continuously displays the monitored 

  gas pressures and vacuum in the piping system

• Facility to program the units of measure for each gas 

  to read in PSI, BAR, and kPa

• Individual monitoring of all the gases using 3 nos 

  Seven segment display

• Visual indicators for system pressure or vacuum are 

  normal (green) and individual indicators (red) for alarm fault condition such as LOW or HIGH pressure

• Low and high alarm points are factory set per 

  standards, but remain field programmable

• Audio and visual alarm indicators with MUTE switch

• Isolated potential contacts for remote annunciator 

  applications

• Battery backup in case of power failure (Optional)

Area Alarm Sensor

• Digitally calibrated sensors. No need of calibration/

  re-calibration at site

• Metallic fixture on Sensor to prevent leakage of

  pressure

• Degree of protection against ingress of liquids IPX0
