شیرهای چک HAWE آلمان
شیرهای چک سرعت جریان را در یک جهت مسدود می کنند در حالی که آن را در جهت دیگر فعال می کنند.
Check valves, type B
Product description
Check valves are a type of non-return valve. They block the oil flow in one direction and open in the opposite direction. In the closed state they have zero leakage.
The check valve type B is available in different housing forms and is suitable for direct in-line installation.
The check valve type B is suitable for usage as a foot valve for a pump suction line due to the low opening pressure.
Features and benefits:
- Flow up to 160 l/min
- Pipe installation
Releasable twin check valve type DRH
Product description
Check valves with hydraulic release are a type of check valve. They block one or both hydraulic consumer lines or are used as a hydraulically actuated drain or circulation valve.
In the closed state the check valve type DRH has zero leakage. It is a twin check valve for double-acting consumers. Available with hydraulic release. Hydraulic release suppresses relief surges that can occur at high pressure and with a large consumer volume.
Features and benefits:
- Pressures up to 500 bar
- with hydraulic release for smooth switching
Check valve and pre-fill valve type F
Product description
Check valves and pre-fill valves are a type of non-return valve. Check valves block the oil flow in one direction and open in the other direction. Pre-fill valves are check valves with hydraulic release. They are used, e.g. in top ram presses for suction and emptying the press cylinder on rapid closing and opening.
The check valve and pre-fill valve type F is a spring-loaded disk valve and has zero leakage in the closed state. The valve is attached directly to the cylinder and clamped between the base of the cylinder and the welding-neck flange. Alternatively the valve is installed in the line between the front faces of the welding-neck flanges.
The valves type F25 - F80 are available with hydraulic release. Hydraulic release suppresses relief surges that can occur at high pressure and with a large consumer volume.
Features and benefits:
- Wafer design
- Extremely large flows, up to 7000 l/min
Intended applications:
- Press control systems
- Injection moulding machines
Shuttle valve type WV and WVC
Product description
The shuttle valve type WV is integrated in a T-fitting for pipe connection. The type WVC is a screw-in valve. The shuttle valves can withstand pressures up to 700 bar and have low flow resistances.
They can be used for transmitting control pressures or control and operating volumetric flows.
Intended applications:- Load sensing systems
- Construction and construction materials machinery
- Cranes and lifting equipment
- Road vehicle
- General mobile hydraulics
