Pilot Operated Relief Valves (BG BT)

These valves protect the hydraulic system from excessive pressure, and can be used to maintain constant pressure in a hydraulic system. Remote control and unloading are permitted by using vent circuits.

 

Pipe Rupture Valve RS

Description

Excavator pipe rupture valves prevent uncontrolled cylinder movement in the event that a pipe or hose bursts. The ESV valve fulfills all of the requirements of the ISO 8643  and EN 474-5 standards for excavators.

Pipe Rupture Valve RS

Description

Pipe rupture valves are used wherever a load must not be allowed to drop rapidly and without control if a pipe or hose bursts (ex. uncontrolled movement of the cylinder). In its normal position the pipe rupture valve is open and allows the flow in both directions. When the actuating flow rate is exceeded – by a hose burst, for example – the pipe rupture valve closes suddenly and blocks flow without leakage.

Note

Due to their very high closing speed, these products are not suitable for applications that iclude the transportation of people. The activation of the pipe rupture valve produces very large declerations that can have adverse health effects.

Precision Orifices

Description

Precision orifices from Bucher Hydraulics are manufactured with close tolerances (+0.02/-0.01) and thus guarantee high flow accuracy. Each orifice is marked with its respective orifice diameter. The orifices are used for throttling and controlling oil flows in all hydraulic applications.

We manufacture burr-free precision nozzles from thread M3 and bore diameters from 0.3 mm. We work primarily with free-cutting steel, other materials are available on request.

Pressure Monitors (DP SJT)

The pressure monitoring system is for watching hydraulic system pressure and is composed of highly reliable pressure sensor (SJT*-02-10) and easy-to-use digital pressure monitor (DP*-*-*-10). There is no specific model number code for the pressure monitoring system itself, therefore, when ordering, specify the digital pressure monitor and pressure sensor with respective model number code.
Remote pressure indication

Even if the monitor is located away from the unit, remote pressure indication can be obtained by combination with special sensors.
Remote-setting pressure sensors

The pressure sensor can be used as a pressure switch with two contacts: top and bottom. Pressure can be set and checked without using any other pressure gauge, moreover, such pressure setting and pressure check can be made when no pressure is applied in the hydraulic system.

 

Pressure Reducing & Relieving Valves (RBG)

Pressure reducing and relieving valves are composite pressure control valves having pressure reducing and counterbalancing functions developed for hydraulic balancing circuits.
