CETOP 8 (NG25) Two Position Hydraulic Valve Body is a high flow capacity control element controlled by a single coil NG6 or NG10 pilot valve mounted on it. These valve bodies with a flow capacity of up to 500-600 L/min are used in heavy duty machines, presses and high pressure industrial systems. Its design in accordance with ISO 4401-08 standard provides easy installation and maintenance. These bodies are generally controlled by a pilot valve. They are also available in direct operated models. Direct acting (coil, electric), hydraulic and pneumatic acting models that do not require control with the NG6 pilot valve are also available.
CETOP 8 (NG25) Two Position Hydraulic Valve Body is a control element used for high pressure flow control in industrial systems. This type of valve body operates with a two position (Open-Close) control mechanism and is controlled by a NG6 or NG10 single coil pilot valve mounted on it. This structure provides fluid direction in the system between two different positions (for example, forward/reverse or open/closed) quickly and reliably.
The design of this body complies with ISO 4401-08 and DIN 24340 NG25 standards, making it an internationally compatible hydraulic control element. The valve body has a flow capacity of 500-600 L/min and can withstand pressures up to 350 bar. With these features, it is widely used in large industrial machines and systems requiring high flow.
This type of valve has a two-position, single-coil control structure. This means that the valve is controlled by only one coil (electrical control). When the coil is energized, the valve changes position. When the coil is de-energized, the valve returns to its original position by spring force . This control mechanism also meets the requirements of fail-safe system shutdown, because when the power is de-energized, the valve automatically returns to a "default" position (e.g. open or closed).
Main Features:
Working Mechanism:
When the Coil is Energized (Active Position):
When the pilot valve is engaged (the coil is energized), the pressurized fluid changes the position of the main valve . This allows the flow in the system to be directed (for example, the flow can be forward or reverse).
When Coil is De-energized (Default Position):
When the pilot valve is disengaged, the main valve is returned to its original position by the return spring . This allows the system to return to a certain safe position when power is removed. This is a critical feature to ensure system safety in press machines and industrial applications where hazardous movements are present.
