Vacuum Regulators are constructed of rugged plastics and metals to withstand full supply pressure. Manually operated valves contain a gas shutoff position to enable container changes without admitting air, dirt or moisture to the control module and without shutting off the injector. These valves are factory set to reduce gas pressure to optimum operating vacuum and can be serviced without disturbing adjustments.
To ensure continuous supply of gas being fed, automatic switchover from an empty container is achieved by a pair of optional vacuum regulating valves. The valve on standby is held closed by a detent-type lockout. When the on line supply is exhausted, system vacuum rises to a higher than normal level. This increased vacuum overcomes the latching force of the detent and the standby supply comes on line. Automatic switchover valves are available only with capacities to 3000ppd.
200 ppd & 500 ppd Vacuum Regulators

The 200 & 500 ppd vacuum regulators are constructed of a moulded PVC housing for corrosion resistance and metal inlet components to withstand full supply pressure.
A unique lever mechanism and front panel knob provides the operator with a quick indication of operation mode. An additional built-in red indicator becomes visible in low/out of gas situations and an optional contact is available for remote indication.

Utilizing a unique pressure check/pressure relief valve designed to minimise the possibility of gas being released to the atmosphere. This is a double check system utilizing two valves that will not open to allow gas flow unless a vacuum is present. In order for gas to be vented, both valves would have to fail, which is extremely unlikely. Vacuum Regulator 3,000ppd Manual |

For reliability with evaporators, the vacuum regulating valve used with the 10,000 ppd module has an electric operator. It's designed to give positive shut off of the chlorine supply should evaporator temperature or water level fall below the operating limit or should power fail. The vacuum regulating valve also has a low temperature switch designed to close the electric operator and activate an alarm in the event of an evaporator malfunction. The electric operator and the low temperature switch are also available with the 3,000 ppd vacuum regulator. Vacuum Regulator 10,000ppd Drawings Vacuum Regulator 10,000ppd Manual |
