HYDRAULIC DRIVE
The most reliable flow control valve on the world market.
Extremely reliable and precise flow control, on/off function, emergency shut-off and different safety operations in the most difficult working conditions.
A source of hydraulic oil pressure used in different types of electro-hydraulic or air-hydraulic power unit. Hydraulic pressure oil is used for drive, water or water emulsions up to 250 bar. Feedback system for valve opennes control is based on internal and external sensors ( type INFB or EXFB)
Drive combinations: single acting with options fail to close, fail to open and double acting.
HD type of the valve drive system for complex valve tasks at difficult working conditions. Reliable hydraulic emergency drive by hydraulic hand pump or accumulator.
Most reliable shut-off function for realization of high integrity pressure protection systems – HIPPS
Feedback system type EXCP.VS
Design with external device for valve openness control.
DN 200_PN16 example design for water application
