Thermostatic Expansion Valves :
Thermostatic Expansion Valves are used to meter the flow of liquid refrigerant entering the evaporator at a rate that matches the amount of refrigerant being boiled off in the evaporator. The valve provides a pressure drop in the system, separating the high pressure side of the system from the low pressure side of the system, allowing the low pressure refrigerant to absorb heat onto itself.

Thermostatic expansion valves are designed for a wide range of air conditioning, refrigeration, heat pump and chiller applications.
Our integral valve line includes valves for commercial and refrigeration applications, as well as heat pump and residential applications. The "Take-A-Part Series" valves are the answer to your unique needs, available for almost any type of application, temperature range, or any known refrigerant. We also offer a complete line of specialty valves. Consult us for your specific system requirements.
The Thermo® Expansion Valve is a precision device designed to regulate the rate of refrigerant liquid flow into the evaporator in the exact proportion to the rate of evaporation of the refrigerant liquid in the evaporator. The amount of refrigerant gas leaving the evaporator can be regulated since the Thermo Valve responds to the temperature of the refrigerant gas leaving the evaporator and the pressure in the evaporator. This controlled flow prevents the return of refrigerant liquid to the compressor. The Thermo Expansion Valve controls the flow of gas by maintaining a pre-determined superheat.

Electronically operated valves for refrigeration systems are used in conjunction with electronic controls, typically from the Danfoss range of ADAP-KOOL® controllers. The range consists of electronically operated expansion valves for refrigeration systems with fluorinated refrigerants and ammonia (R717), evaporating pressure valves, and evaporating pressure pilot valves that enable electronic and remote operation of a PM main valve.

Thermostatic Expansion Valves are available as parts programme, i.e. with separate valve body and orifice assemblies, or as complete valves (fixed orifice).The category also contains Thermostatic Injection Valves.

Red Valve manufactures a complete line of Redflex® Expansion Joints, rubber fittings and rubber pipe. Expansion joints are designed to alleviate piping stress, compensate for movement, reduce noise, and isolate vibration. Redflex® products can be custom-built in a variety of styles and configurations to accommodate pipe size reductions, misalignments and offsets. Red Valve offers flanged and slip-on connections, single or multiple arches, and a range of elastomers to meet process conditions, including Teflon-lined joints for severely corrosive applications.
The Redflex® product line also includes rubber fittings, rubber elbows, vibration pipe, and rubber pipe to accommodate radius turns. The Red Valve Company also custom builds many unique rubber products, such as headers with multiple pipe connections.
