Core concept

Focusing on fluid medium control, providing customized, highly reliable, and long-life valve solutions

Core technological advantages of coaxial valves

Technical highlights and core values

The pressure balance design can start at 0 bar without the need for a minimum pressure difference

Bidirectional flow medium can flow in both directions, reducing the number of valves

The pressure on the outlet side of the back pressure seal is higher and there is no leakage

Maintenance free single moving parts, no valve stem seal, strong stain resistance

High speed response switch time * * ＜ 30ms * *, with a lifespan 10 times that of conventional valves

Energy saving technology Green Line series reduces energy consumption by 80%, and the coil does not heat up

Key issues

Question 1: What are the core technological advantages of m ü ller co ax coaxial valves compared to conventional valves?

Answer: The core advantages are pressure balance design (starting at 0 bar), bidirectional flow, back pressure sealing, maintenance free, high-speed response<30ms; the Green Line series can save 80% energy, the coil does not heat up, the service life is 10 times that of conventional valves, and it has strong pollution resistance without daily maintenance.

Question 2: What is the pressure and caliber range covered by M ü ller Co ax products, and what are the key certifications?

Answer: The caliber covers DN1.5-DN250, with a pressure range of 0-500 bar; Key certifications include DIN EN ISO 9001, PED, ATEX, DVGW, T Ü V, SIL2/SIL3, meeting high requirements scenarios such as explosion-proof, gas, fuel, and safety circuits.

Question 3: What are the technical principles and actual effects of the Green Line energy-saving series?

Answer: Using a patented electronic control system, the direct acting valve (MK/FK series) can automatically reduce coil power consumption by 80%; Equipped with damping switch, no impact, position feedback, power-off spring reset, the coil does not generate heat throughout the entire process, greatly improving stability and lifespan.
