Electric three-eccentric metal hard seal butterfly valve

INTRODUCTION

Motorisable butterfly valve features
1.Protection of gearbox IP 68-8 (submersion up to 8 m of water) and actuator IP 68 (submersion up to 8 m of water, during 96 hours and 10operations)
①With position indicator.
②Clockwise Close (CC).
③For installation above ground and in non-flooded chambers.
④Designed and tested to an endurance level of 2500 cycles minimum, inaccordance with EN 1074-1 and 2.
⑤Supplied with a handwheel.

2.Reduces resilient seal’s wear and tear ensuring detachment from the body seat ring the moment the valve begins to open.
①reduces pressure loss in fully open position by the disc
②parking in a zone of reduced flow.
③lower torque requirement to rotate the disc leads to less
④wear and longer life of the gasket and other elements.
