Aqua Environment 955-R 955 Series Check Valve 1/4" NPT Female to Male Flow 6000 PSI

The model 955 check valve permits flow in one direction only thus eliminating the possibility of back flow. It is suitable for any noncorrosive gas or liquid flow. The simple reliable design uses O ring seals to insure bubble tight sealing even with very low back pressures. It can be used as a direct replacement for model 594, 1/4" check valve and offers higher flow capacity. To permit use in a variety of systems the flow direction can be reversed by reversing the poppet. Flow is from the male thread end to the female end unless the opposite direction is requested. Flow direction as assembled is shown on the label.

Features:

• Check valve
• 1/4 in. NPT
• Female to male flow

Installation

Observe the flow direction noted on the label. The standard valve flows from male to female thread unless special ordered. Flow can be reversed by disassembling and reversing the position of the poppet and spring as shown below. Use a suitable pipe thread sealant such as teflon tape on inlet and outlet threads. Avoid over torquing pipe thread. Normal torque applied with a 6 or 8 inch long wrench is ample. Use ample teflon tape - 3 or 4 turns, not 1 or 2 turns. The regulator is NOT shipped oxygen clean and should NOT be used for oxygen service as provided.
