features and benefits
LOW TORQUE, LOW CLOSING FORCES
The Hydrocore™ oil-hydraulic isolating valve is hydro-statically balanced, requiring very low operating torque or operating forces at all valve positions and for all valve sizes and all pressure ratings.
No gearbox is required to assist in the valve's opening and closing for the Hydrocore™ oil-hydraulic isolating valve. The valve is hydro-statically balanced and requires very low operating forces.
The Hydrocore™ oil-hydraulic isolating valve is simple and reliable with a robust construction. Very little maintenance is required, it can be undertaken by semi-skilled personnel and with a short downtime period.
Seat Leakage - B16.104 class III, IV, V or VI, depends on valve type and application.
Principles of Operation
Once an electrical signal is given, the solenoid valve switches over, hydraulic fluid enters the cylinder opening compartment and pulls the valves shuttle towards the open position. Once power is removed the solenoid valve switches to the original position, hydraulic fluid enters the cylinder closing compartment and pushes the valve shuttle to the closed position. In the event of a power failure, the power pack’s accumulator, provides enough oil pressure and oil
The oil-hydraulic valve's actuator is a natural and integrated part of the valve. This type of actuator is ideal for plants or pump stations, where a hydraulic power pack can energize many valves. The advantages of the oil-hydraulic actuation are:
areas of applications
The Hydrocore™ oil-hydraulic isolating valve is used for remote isolating of pipeline applications and mainly used in:
