MNH 520 701 VES/KES:5/2�way double solenoid valve actuated by impulse. Position is kept until an electrical signal is applied to the opposite side even when not attached to electrical source. Interface in accordance to Namur 1.

DRN 3 611 VES, DRN 5 611 VES, DRF 3 611 VES:Block form flow regulators as intermediate plate. Interface according to Namur 1.

Pneumatically actuated valves are available on request.

Hafner is offering a selected range of pneumatic control valves entirely made of stainless steel 316L / 1.4404.

Basically we distinguish between two different versions, VES and KES.

At the VES�version the pilot head is made of 316L / 1.4404 stainless steel, seals are made of PUR and other rubber�parts are made of FKM.

At the KES�version the pilot head is made of PA, seals are made of PUR and other rubber�parts are made of NBR. The KES�version is the more economic solution.

For further technical information, please refer to the respective data�sheets enclosed.
