FAQ

Q1: What types of Blait semi-hermetic valve plates are available? How do I select the right one?

We offer three types: flat-plate valves, annular valves, and lift valves. Flat-plate valves are suitable for medium- and low-pressure applications, annular valves are suitable for high-pressure systems, and lift valves are suitable for precision, low-noise applications. Selection should be based on the compressor model, operating conditions, and refrigerant; please contact technical support for recommendations.

Q2: What material is the valve plate made of? Is it corrosion-resistant?

The main body is made of high-quality stainless steel, with optional Inconel or coated alloys available. It can withstand high pressure, rapid start-stop cycles, and corrosive gases (such as H₂S).

Q3: How do the valve plates help save energy?

Optimized through CFD thermodynamics to reduce gas flow losses, they lower compressor energy consumption while ensuring a reliable seal.

Q4: Which industries and refrigerants are they suitable for?

Commercial/industrial refrigeration, cold chain, food processing, chemical, medical, and more. Compatible with common refrigerants such as R22, R134a, R404A, and R410A.

Q5: What is the service life and maintenance interval?

It can withstand millions of cycles and is designed with replaceable components (springs, valve seats). We recommend regularly inspecting for wear and replacing worn parts in a timely manner.

Q6: Is installation complicated?

We recommend that installation be performed by qualified technicians in accordance with the compressor installation manual. Blait can provide detailed installation instructions.

Q7: Can it be customized?

Yes. We offer customized solutions for material upgrades, dimensions, performance, and more to meet the needs of different compressor systems.

Q8: What quality certifications does Blait hold?

CE certified and compliant with ISO 9001, ISO 14001, and ISO 45001 standards. Products undergo rigorous testing for leaks, cycle life, and other parameters.
