structural composition
Block Body
The aluminum alloy precision-machined integrated valve body features internally interconnected flow channels; the front yellow protective ring serves as the primary oil inlet and outlet, with standard mounting screw holes for filter cartridges reserved on the plate surface, and a pressure differential transmitter installation interface provided on the side. The flow channel layout is optimized to minimize pressure loss.
Double-group manual reversing mechanism
Equipped with two stainless steel operating handles and an internally replaced directional valve core.Switch the oil circuit on/off by operating the handle to precisely isolate individual filter cartridges, ensuring reliable switching positioning and preventing accidental operation.
Sealing system
Equipped with oil-resistant sealing components to ensure no internal leakage and prevent media bypass or short circuits under switching conditions.

Optional configurations
- The accompanying filter cartridge housing contains the built-in filtration element.
- Install a differential pressure transmission device.
- Customized inlet and outlet ports: flange or threaded specifications are available upon request.
- Customizable stainless steel valve bodies are available for special operating conditions (suitable for corrosive media such as water and ethylene glycol).

FAQ
Q: How long is your delivery time?
A: Generally it is 3--5 days if the goods are in stock, or it is 10--15 days if the goods are not in stock, also according to the quantity you need.
Q: How does a backwash filter work?
A: The backwash is an operation in which water passes backward through the filter at a rapid rate. It enters the tank at the bottom via the riser tube, then passes upward through the filter medium, exiting at the top, via the control valve.
Q: What is the backwash filter on a ship?
A: Auto Back wash filter: An auto backwashing filter is a self-cleaning filtration system that automatically reverses the flow of water or fluid through the filter media to remove accumulated debris and maintain its efficiency.
Q: What is a backflush filter?
A: A backflushing filter is a type of filter that removes impurities or contaminants from low viscosity liquids like lubrication oils and fuel oil.
Q: Consequences of Malfunctions in the Control Valve Spool?
A: 1.External leakage of the valve body.
2.Loud fluid flow noise when the handle is in the working position, and slow movement of the upright column or jack.
3.Slow movement of the hydraulic support upright column and jack, accompanied by pressure blocking.
