Müller CO-AX Valves valve principel - Type MK/FK
co-ax valves are not just another "valve-in-a-box". Using a wide selection of orifice sizes, port connections, seal and seat configurations, our experienced application engineers tailor valves for maximum performance in your application. Whether you need one valve or one hundred. Simple shut-off valves to flow or pressure control, single valves or multiple valve manifolds, we can save you space, time and money!

• Coaxial valves have a single moving part: the control tube (a).
• When the control tube is actuated by an electromagnet (Figure A) or a pneumatic / hydraulic signal to the actuator (Figure B) the tube moves away from the valve seat (b).
• This allows the media to flow straight through without deviation. Powering the tube back against the seat closes the valve. The tube is held against the seat independent of system pressure. This provides positive shut-off and compensates for seat wear.Dynamic seals (c) prevent shaft leakage.
• Valve are pressure balanced 2/2 way direct acting coaxial valves, NC and NO versions​
• Optimized for gaseous, liquid, gelatinous, highly viscous, pasty, contaminated, aggressive
• ​Certificates PTB (Ex), TÜV, DVGW
