Our aim is to provide complete system and application solutions that meet the specific needs of our customers. Tell us what you need and we will find an appropriate solution using our vast experience.
Servo Assisted Solenoid Operated Valve
(2/2 & 3/2) NO or NC 0,3 to 150 bar
G ¼” – G3” Flanged up to DN250
Valves of this design are distinguished by a simple, solid construction. The sealing of this valve is, either a diaphragm for pressures up to 20bar, or a robust piston for pressures of up to 100 bar and more. By use of a small pilot orifice, the valve utilises the line pressure differential to operate the valve. Thus only needing comparatively low coil power for high flow & pressure characteristics.
For “Normally Closed” constructions, when the solenoid is energised, the pilot orifice is opened and releases pressure from the top of the valve diaphragm or piston to the outlet of the valve. This results in an unbalanced pressure which forces the line pressure to lift the diaphragm or piston off the main orifice thereby opening the valve. When the solenoid is de-energised, the pilot orifice is closed and the full line pressure is applied to the top of the diaphragm or piston through the bleed orifice, thereby providing a sealing force for tight closure.
Force Pilot Operated Solenoid Valve
(2/2) NO or NC 0 to 40 bar
G 1/4 - G2” Flanged up to DN300
No differential pressure is necessary for the valve to operate. This construction combines Servo-assisted lift with Direct actuation and consequently combines the advantages of both control methods.
For “Normally Closed” constructions, when the solenoid is energised, the pilot orifice is opened and releases whatever pressure there is from the top of the valve diaphragm or piston to the outlet of the valve. The diaphragm or piston is mechanically held to the magnetic core, and can open the valve with zero differential. When the solenoid is de-energised, the pilot orifice is closed and the full line pressure is applied to the top of the diaphragm or piston through the bleed orifice. If there is little or no pressure, the spring force closes the valve.
Direct Operating Solenoid Valve
(2/2 & 3/2) NO or NC 0 to 100 bar
G 1/8” - G 2”
In a direct acting solenoid valve the solenoid core is mechanically connected to the valve disc and directly opens or closes the orifice. This construction does not rely on differential pressure. Three factors have to be taken into consideration and a compromise made which depends upon the orifice size – operating pressure differential – magnetic force of the coil.
These valves are often used for small nominal sizes, low pressure and vacuum.
Externally Controlled Pilot Piston Operated Valve
(2/2 & 3/2) NO or NC 0 to 25 bar
G ¼ - G3” Flanged up to DN300
This construction uses an external media pressure source, often air, to pressurise the actuator. With 3/2 way pilot solenoid valve diverts the external pressure source to the internal chamber of the actuator to move the piston against the force of the controlling spring. These valves are suitable for the control of contaminated, aggressive, viscous and high temperature media. The actuator is separated from the medium.
Motorised Valve
(2/2 & 3/2) 0 to 40 bar
G ½” - G3” Flanged up to DN300
This construction uses an external media pressure source, often air, to pressurise the actuator. With 3/2 way pilot solenoid valve diverts the external pressure source to the internal chamber of the actuator to move the piston against the force of the controlling spring. These valves are suitable for the control of contaminated, aggressive, viscous and high temperature media. The actuator is separated from the medium.
