Aqua Environment 969 969 Series Hand Load Reducing Regulator 1/4" NPT 0-250 PSI Out

The model 969 is a small, economical piston type spring loading regulator. The poppet assembly is contained in a cartridge with internal filtration for easy in-field changing. The regulator is self venting. It is suitable for either gas or liquid service.

Features:

• Hand Load Reducing Regulator
• 1/4 in. NPT
• 0-250 PSI out
• Single outlet
• Economical

Installation

Use a suitable pipe thread sealant such as teflon tape on the 1/4" inlet and 1/8" outlet connections. The 1/8" port is the outlet. The 1/4" thread at the bottom is the outlet. Connect the inlet to the source gas such as a high pressure storage tank. The outlet is capable of being adjusted from 0 to 250 PSI. AN OUTLET GUAGE AND RELIEF VALVE SET NO HIGHER THAN 250 PSI SHOULD BE CONNECTED TO THE OUTLET. IF THE INLET PRESSURE CAN EXCEED 6000 PSI A RELIEF VALVE SHOULD ALSO BE INSTALLED AT THE INLET TO PREVENT EXCEEDING 6000 PSI.

Avoid overtorquing pipe threads. Normal torque with a 6 or 8 inch wrench is ample. Use anple teflon tape - 3 or 4 turns, not 1 or 2.. The lower one inch thread section can be used for mounting in a one inch hole punched in a mounting plate or panel. The regulator is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.

Operation

Operation is very simple. Outlet pressure is adjusted by the pressure adjusting screw to the desired value as read on the outlet gauge. When reducing the pressure the regulator will self vent via the vent hole near the cap. This is normal. When reducing set pressure reduce pressure to below the new setting then increase pressure to the new setting.
