New Generation Design Valves (Back To Top)

Valves are a very important part of the piping technology and are mainly used for isolating, control and safety applications in the fluid transfer field.
The N.G.D Valve series is a new and entirely unique concept in the valve industry, which make possible the automatic control and safety functions, for fluid transfer system, without any pilots, instruments, controllers, power supply or computers. In simple words it can be described as a simply magic as it offers high-tech applications without the associated conventional high-tech technology.

Uniqueness of the N.G.D Valves (Back To Top)

The N.G.D Valve series is the right product in the right time when one considers the urgent need for simple automation of existing plants and pipeline systems, in the world and especially in Africa. The N.G.D Valve series provides a bargain deal for plant automation, without the associated high-tech equipment and without the required high-tech skilled personnel, mostly when the following benefits are considered: -

• Reduction in the number of plant operators.
• Minimization of the need for high-tech skilled personnel.
• Reduction in the sophistication level of the plant control.
• Prevention of damages to plant, pipeline & equipment, due the human error or human negligence and as a result the saving of repair and loss of production costs.
• Reduction in capital cost for new plants.

N.G.D Valves - Main Features (Back To Top)

The N.G.D valve series has many advantages of which the most important are listed below: -

• The N.G.D valves do not require an external actuator, as the valve's piston itself is a simple and powerful pneumatic/hydraulic actuator.
• Handwheel and electrically actuated valves do not require the torque assistance of a gearbox.
• The valve's piston serves as the control pilot for all of the line-actuated safety and control valves with less vulnerability to precipitation or the build-up of corrosion products.
• All of the N.G.D safety and control valves can be used as a conventional or I/P actuated control valves by utilising conventional transmitters, switches and controllers.
• All of the self-powered N.G.D safety and control valves are not accessible to unauthorised tampering with the valve's pre-set parameters.
• The sealing arrangement of the N.G.D valves is of the pressure-assisted type, inducing low magnitude of parasite friction forces.
• All of the N.G.D valves are maintainable while in-line.
• No other parts of the valve are inserted into the valve body except for the valve piston, which serves as a carrier to all of the seals and the valve seat.
• Most of the N.G.D valve parts are interchangeable between the various applications, irrespective of the pressure rating.
