Being able to control flow, flow rates and flow direction, is critical to many processes. Depending on process flow, pressure and media, different types of valves need to be utilized. Ball valves, needle valves, solenoid valves, butterfly valves and pressure relieve valves, are some of the more common valves used on board ships. Furthermore, most valves can be remotely operated via actuators and signals.
Double and single acting actuators for valves with 90 ° rotation. The side stops can be adjusted by ± 10 ° so that max. rotation is max 110 ° and min. Is 70 °. However, can be changed to higher or lower on request. The actuators are lifetime lubricated.
It is possible to mount a gearbox between actuator and valve, which can be used in emergency situations, eg. in the absence of compressed air. The gearbox is disconnected during normal operation and can be quickly activated by means of a handle so that the handwheel of the gearbox can be operated.
Electric actuator from Ghibson, adapted to their butterfly valves and ball valves. Media temperature from -20 ° C to + 70 °C and protection class IP 67 (IP 68 on request).
Quarter-turn electric actuator "NA series" is designed to operate ball valves and butterfly valves. The actuator is strong and robust.
Ghibson’s own manufactured hydraulic actuators (ARES series) are designed to fulfill the specific requirement in industrial applications: compact design and high performance are the main characteristicsof this product range.
AUMA has a generally modular product concept. From a wide range of modules, you can tailor actuators for any application. Clear interfaces between the individual components make it possible to utilize the many variants - always with high demands on the quality of the products and the ease of use of the AUMA actuators.
The Compact ™ actuator from Habonim, with its 4-piston design and short piston travel, ensures a fast-acting actuator. The compact design is space-saving and results in approx. double torque versus a corresponding 2-piston actuator. Thus, the same torque can be achieved with a smaller actuator from Habonim, which lowers air consumption per activation.
The cryogenic ball valve from Habonim can be installed at an angle up to 45 ° and with an upstream pressure equalization hole in the ball, Habonim ensures that no pressure builds up due to heat expansion. The valve is clearly the direction mark, which provides an easy installation.
Habonim line of 3-piece ball valves is engineered for endurance and meet the most demanding industrial and international standards. The 47 series, is designed and manufactured for applications with high-flow capacity and tight shutoff, to ensure reliability and functionality.

Basic – but Essential to Operations
Valves are used for many purposes and are available in just as many varieties. The basic function of a valve is to create a variable barrier between the two sides of the valve. Valves are most commonly used for three purposes; open/close, control or safety. Depending on what the valves’ intended use is, the characteristics can be very different in regards to shape, size and materials.
As valves are one of the most common items found on board most ships, they are crucial for the operation, functionality and safety of the vessel. It is therefore, critical to have them functioning and well maintained at all times. If the wrong valve malfunctions at the wrong time, it could lead to delays, additional cost and in the extreme case even disaster. Apart from the valves themselves, all the directly related components are just as vital, and whether it is an actuator, a postioner or a switch, the failure of one of these ‘sub components’ could have the same affect as a failing valve.
