FLOW CONTROLS

CHECK VALVES

Globe Design

The function of a Check Valve is to allow fluid flow in one direction

only.

Applications

A typical application is to install a Check Valve downstream of an Oil

Separator. This prevents condensed liquid refrigerant from returning down

the discharge line and into the Separator. Henry Technologies’ Check Valves

are suitable for use with HCFC and HFC refrigerants and their associated

oils, as well as other industrial fluids non-corrosive to brass, steel, copper,

Teflon and synthetic rubber.

Technical Specifications

Maximum working pressure = 500 PSI (34.5 Bar)

Allowable operating temperature = -20°F to +300°F (

Typically, Henry Technologies’ Check Valves will start to open at 0.5 PSI and

be fully open at 5 PSI pressure differential.

Series 116 and 205 Check Valves are USR and CNR recognized by

Underwriters Laboratories, Inc.

-29°C to +149°C)

Materials of Construction

The valve body on the 116 series is made from brass and the valve body on

the 205 series is made from cast bronze. The piston is made from brass.

the spring is made from stainless steel. The seat is made from PTFE.

Installation - Notes

1. Valves must be installed in accordance with the flow direction arrow.

2. The valve bodies and valve internals must be protected against damage

during brazing. Piston must be removed for brazing. Full instructions are

given in the Product Instruction Sheet, included with each valve.

3. Series 116 valves can be installed in any position except bonnet down.

Series 205 valves sizes 7/8” - 1-3/8” can be installed in any position

except bonnet down, however, 205 valves sizes 1-3/8” - 2-5/8” MUST be

installed with bonnet positioned upwards. For all models, the

recommended bonnet position is upwards.

4. Discharge Check Valves should be positioned as far from the

compressor as possible.
