Safety Information

Important – Please read before installation
These instructions contain DANGER, WARNING, and CAUTION labels, where necessary, to alert you to safety related or other important information. Read the instructions carefully before installing and maintaining your control valve. DANGER and WARNING hazards are related to personal injury. CAUTION hazards involve equipment or property damage. Operation of damaged equipment can, under certain operational conditions, result in degraded process system performance that can lead to injury or death. Total compliance with all DANGER, WARNING, and CAUTION notices is required for safe operation.

 This is the safety alert symbol. It alerts you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.

Danger
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
Warning
Indicates a potentially hazardous situation which, if not avoided, could result in serious injury.
Caution
Indicates a potentially hazardous situation which, if not avoided, could result in minor or moderate injury
Caution
When used without the safety alert symbol, indicates a potentially hazardous situation which, if not avoided, could result in property damage.

Certifications

This instrument is certified in:

• Azerbaijan (AzSERTCENTER)
• Armenia
• Belarus
• Kazakhstan
• Russian Federation (CU-TR Ex)
• Uzbekistan (UZSTANDART)
• and is also ATEX compliant.

Installation

Clean the lines thoroughly to remove all dirt, scale or other foreign matter before installing the regulator. Install with flow in direction of flow arrows on regulator body. The airset should be installed with the drain cock facing down. Regulator should be installed as close as possible to device utilizing the reduced pressure to minimize pressure drop. Do not use piping or tubing smaller than the regulator connections since this will restrict flow and reduce capacity.
It is recommended that pressure gauges be installed on the inlet and outlet sides of the regulator as an aid in adjusting the pressure and in monitoring of working pressures.

Operation

Prior to applying supply pressure, loosen knob lock screw and turn pressure set knob counterclockwise. Turn on supply pressure. Output pressure should be zero. Slowly rotate set knob clockwise until desired pressure is reached. Tighten knob locking screw to ensure that pressure remains set at desired value. When changing output from a higher to lower pres¬sure, initially go to lower than desired pressure, then increase to desired pressure. Re-tighten knob lock-screw.

Maintenance

It is recommended that the drain cock be opened at regular intervals to drain any fluid that may have collected in the dripwell. The interval between draining will have to be determined based on the actual rate of accumulation of fluid.

It is recommended that pressure gauges be installed on the inlet and outlet sides of the regulator as an aid in adjusting the pressure and in monitoring of working pressures.

WARNING
The relief valve feature should not be confused with any auxiliary safety valve which might be needed for complete protection of air operated equipment. It is intended only to provide more uniform controlled pressure and to permit adjusting the outlet pressure downward without venting the line.

WARNING
Prior to performing maintenance on the regulator, shut off the inlet and outlet pressures and remove the spring compression by turning the setting knob fully counterclockwise. Open the drain cock carefully to relieve any retained pressure and drain the drip well. It is recommended that the regulator be removed from the line for repairs.

CAUTION
When draining the drip well, open the drain cock slowly and collect the fluid in a suitable container for safe disposal.

NOTE:

• Considering the high labor costs involved in replacing internal parts, it may be more economical to stock complete units.
• Care must be taken to avoid damage to the plug and stem assembly.

Troubleshooting

If at any time the regulator fails to function properly it is recommended to replace rather than repair the device.
