Aqua Environment 1262-1500-B 1262 Series Reducing Regulator Dome Loaded Amplifying Regulator Brass Wetted Surfaces

The model 1262 is a reducing regulator wherein outlet pressure is controlled by lower pressure control air applied to the control port. Outlet or regulated pressure will be 15 times the control pressure used. This permits using shop air or other low pressure source to provide an accurately controlled high pressure regulator. By using air rather than a spring to set pressure the regulator can be controlled remotely and pressure changes can be made much more rapidly. The 1262-1500 includes a baffle under the control piston to reduce effects of vent pressure on controlled pressure.

Features:

• Reducing Regulator
• Dome Loaded Amplifying Regulator
• 1/4 in. NPT
• 15:1 amplification
• 0 to 1500 psi outlet
• Brass wetted surfaces

Installation

Use a suitable pipe thread sealant such as teflon tape on the 1/4" inlet and 1/4" outlet connections. Connect the inlet to the source gas such as a high pressure storage tank. AN OUTLET GAUGE AND RELIEF VALVE SET SLIGHTLY HIGHER THAN THE DESIRED OUTLET PRESSURE 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 over torquing pipe threads. Normal torque with a 6 or 8 inch wrench is ample.

Use ample teflon tape - 3 or 4 turns, not 1 or 2. The cylinder item 10 can be rotated to position the vent port as desired by loosening the jam nut item 5. The regulator is NOT shipped oxygen clean and should NOT be used for oxygen service as provided. Mounting can be done by clamping to inlet and outlet piping or by providing threaded mount holes in the bottom of the body item 1. Avoid intercepting the body ports. The regulator can be mounted in any position. The vent port can be oriented in any position by rotating the cylinder item 10. If the cylinder cannot be rotated by hand easily loosen jam nut item 5 slightly. The jam nut can be loosened by inserting a 1/8" pin or drill in the holes provided.

Operation

Outlet pressure can be adjusted by varying control pressure at the control port. The outlet pressure will be 15 times the control pressure.

Maintenance and repair caution

As with any regulator or valve, particulates or moisture can plug or freeze the internal filter or valve seat. This can occur when up-stream dryers are not changed or remain unused for long periods allowing corrosion materials to accumulate. In critical applications where it is important not to lose flow, a larger particulate filter should be used upstream.
