Frequently asked questions (FAQs) about Parker refrigeration valves
What are Parker refrigeration valves used for?
Parker refrigeration valves help control, isolate, regulate, or protect flow in industrial refrigeration systems. Depending on the valve type, they may be used for expansion, pressure relief, check flow, shutoff, purging, or main valve service.
What types of Parker refrigeration valves does IRPC carry?
IRPC carries Parker Refrigerating Specialties valves and valve components, including safety relief valves, hand expansion valves, stop/check valves, check valves, access valve kits, water purger valve kits, electro valves, weld neck valves, socket weld valves, butt weld valves, and main valve seat kits.
How do I choose the right Parker refrigeration valve?
Start by matching the Parker part number, valve series, valve size, connection type, pressure rating, refrigerant compatibility, and system function. If you are replacing an existing valve, the part number and valve tag are usually the best starting points.
What is a Parker hand expansion valve?
A Parker hand expansion valve is used to manually control refrigerant flow in an industrial refrigeration system. These valves are often selected by valve size, connection type, body style, and application requirements.
What is the difference between a check valve and a stop/check valve?
A check valve allows flow in one direction and helps prevent reverse flow. A stop/check valve combines check valve function with shutoff capability, allowing the valve to be manually closed when service or isolation is required.
What are Parker safety relief valves used for?
Parker safety relief valves help protect refrigeration equipment from excess pressure. They are selected based on pressure rating, inlet and outlet size, system design, and applicable safety requirements.
What do socket weld and butt weld mean on Parker valves?
Socket weld and butt weld describe how the valve connects to piping. Socket weld connections insert the pipe into a recessed socket before welding, while butt weld connections join the pipe and valve end directly edge to edge.
Can Parker Refrigerating Specialties valves be used in ammonia refrigeration systems?
Many Parker Refrigerating Specialties valves are designed for industrial refrigeration applications, including ammonia systems, but compatibility depends on the specific valve, material, pressure rating, and application. Always confirm product specifications before installation.
Can I replace a Parker valve with another valve brand?
Sometimes, but the replacement must match the valve function, size, pressure rating, connection type, material, refrigerant compatibility, and system requirements. For critical refrigeration systems, it is best to confirm compatibility before substituting brands.
What information should I have before ordering a Parker refrigeration valve?
Have the part number, valve series, valve size, connection type, pressure rating, application, refrigerant type, and any markings from the existing valve. Photos of the nameplate or installed valve can also help confirm the correct replacement.
