Frequently Asked Questions (FAQs) about Expansion Valves

What is an expansion valve in refrigeration systems?

An expansion valve is a critical component that controls the flow of refrigerant into the evaporator, creating the pressure drop necessary for the refrigeration cycle. In industrial refrigeration systems, expansion valves regulate system capacity, maintain proper superheat, and ensure efficient operation under varying load conditions.


What types of expansion valves are available for industrial refrigeration?

Several types are available including globe and angle valves like Parker's T5/T6 series, float valves like Phillips 101A series, and orifice assemblies from Danfoss. Each type offers specific advantages depending on your system requirements, with options for manual adjustment or automatic operation based on system conditions.


How do I choose between globe and angle expansion valves?

Globe valves (like Parker's T5F and T5VAF series) are designed for in-line installation where straight-through flow is preferred, while angle valves (such as Parker's T6VAF series) work better in tight spaces or where a 90-degree change in flow direction is needed. The choice depends primarily on your piping configuration and space constraints.


What connection types are available for expansion valves?

Our inventory includes expansion valves with various connection types including weld neck (WN) connections like Parker's T5VAF series, socket weld (SW) options like the T51F series, and threaded (FPT) connections such as the T52F models. The appropriate connection type depends on your existing system configuration and installation requirements.


How do Phillips float valves differ from Parker expansion valves?

Phillips float valves like the 101A MLB series operate based on liquid level rather than pressure differential, making them ideal for maintaining constant liquid levels in vessels. Parker's HV expansion valves are primarily pressure-reducing devices designed to control refrigerant flow based on system conditions. Each serves different functions in industrial refrigeration systems.


What maintenance is required for expansion valves?

Regular inspection for proper operation, checking for leaks around connections, and verifying correct superheat settings are essential maintenance tasks. Parker valves with stainless steel construction (SS models) offer extended service life, while components like replacement caps should be kept on hand for emergency repairs.


How do I select the correct size expansion valve?

Sizing depends on factors including refrigerant type, system capacity, operating temperatures, and pressure drop requirements. Generally, larger valves like Parker's 4" T5F-R handle higher flow rates for larger systems, while smaller valves such as 1/2" and 3/4" models are appropriate for lower capacity applications or branch lines.


Are stainless steel expansion valves worth the higher cost?

Parker's stainless steel expansion valves (SS designation in models like T5VAF-R SS) offer superior corrosion resistance and longer service life, particularly in harsh environments or when using corrosive refrigerants. While they represent a higher initial investment than standard models, they typically provide better long-term value through extended service life and reduced maintenance.


What's the difference between hand expansion valves and thermostatic expansion valves?

Hand expansion valves (HV) like those from Parker require manual adjustment to set the desired flow rate and superheat, while thermostatic expansion valves automatically adjust to maintain constant superheat based on sensing bulb temperature. Hand valves offer simplicity and reliability in stable operating conditions, while thermostatic valves provide better performance in systems with varying loads.


How quickly can I receive an expansion valve for emergency replacement?

We maintain over 400 expansion valves in stock ready for immediate shipping across Canada and the US. Popular models from Parker, Phillips, and Danfoss can be expedited for emergency situations, helping minimize your system downtime. Our flexible return policy ensures you can shop with confidence even when ordering under urgent circumstances.
