Control valve with greater precision and less turbulence

With a sliding-gate control valve, you are assured of a number of benefits not found in traditional globe-style valves.

The sliding-gate principle is an amazingly simple concept that offers better performance and a wide range of benefits compared to other types of control valves.

Sliding-gate control valve

The sliding gate consists of two primary parts: a movable disc and a stationary plate with several openings. The disc slides back and forth to open and close, and when the valve is closed, the disc overlaps the openings in the plate, ensuring that the valve closes.


The control element in the sliding-gate valve is mounted perpendicular to the flow in contrast to traditional valves. The direct flow in the sliding-gate valve reduces turbulence and provides superior service life.


Outstanding flow control

With a sliding-gate valve you get exceptionally high flow control, as the flow works with the valve and not against it. The fluid presses the disc against the plate, thus helping to maintain the desired precision.


A sliding-gate valve has a very short transfer, which provides fast response, so it is possible to achieve very precise and fast control. This also helps to reduce the actuator size, reduce energy consumption and ensure the control valve a lower weight.


Easy maintenance and long service life

As the valve closes when overlapping, the effects of wire draw are reduced, which is one of the most common causes of leakage. In addition, the slit openings of the valve cause the eroding flow to spread into several less harmful flows.


Thus, wear does not occur at individual points, but the wear is distributed in several places, which results in longer life for the valve.


In addition, the valves are made of the high-tech Jorcote material, which is extremely hardy and delivers outstanding durability. All this ensures the valves a long service life.


Together with the simple design, which makes maintenance easy to carry out (disassembly of the valve is very simple, and since the parts are not pressed or screwed into the valve housing, they can be conveniently lifted out), the long service life means less downtime for maintenance.


Less noise and lower footprint

Sliding-gate valves make less noise than other types of valves, partly because the laminar flow minimizes turbulence, which is the main cause of valve noise in globe-style valves and rotary valves. In addition, the many orifices in the plate and disc divide the flow into smaller streams, resulting in less noise.


The pressure in the valve will keep the disc in constant contact with the plate. This prevents the sudden, damaging (and noisy) contact that occurs in some valves.


The constant contact between the disc and the plate creates a self-lapping effect, which results in less friction and causes the valve to actually close more tightly over time than when, as new, it leaves the factory.


The movement of the disc and the plate towards each other is also a self-cleaning movement that effectively removes excess residues of material.


As production lines get bigger and bigger, there is also a need for bigger and heavier valves. Due to the shorter stroke length, sliding gate valves are typically smaller and lighter than alternative valves, thus minimising factory footprint.


Laminar flow ensures less turbulence

The curved flow path in a globe-style valve causes the liquid to change direction several times, resulting in energy loss. In addition, the changes of direction create greater turbulence as well as more noise and wear. This reduces service life and decreases control.


In a sliding-gate valve, on the other hand, there are more orifices and direct flow, which reduces turbulence and leads to a more stable operation, reduced wear, longer service life and better control. Combined with the ultra-compact wafer design, erosion of the valve housing is largely eliminated. This means that dramatic savings can be achieved.
