Monitored Cetop Hydraulic Valve | HBV36

The Dual directional control valves has to be mounted on a specially manufactured manifold for hydraulic safety applications in Cetop 3 or Cetop 5 sizes supplied in a four port two position single solenoid format.

• The valve monitoring system is primarily designed as an interface between the fluid power operation of a machine and the electrical safety circuits monitoring gates, guard and emergency stop circuits.
• The monitoring function can provide for detection of a single valve fault including change of switching times, sticking valve or spontaneous change of state as per the requirements of Australian Standard AS4024.1 Safety of Machinery, Part 1501 Design of safety related parts of control systems – General principles and European Standard EN954-1 Safety of Machinery – Safety related parts of control systems.
• The systems are additionally suited to the monitoring requirements of machine specific standards such as AS1219 Power Presses-Safety Requirements, EN693 Safety of Hydraulic Presses and EN692 Mechanical Presses.

Hydraulic System

• The Hydraulic system comprises two Cetop 3 or Cetop 5 Eaton valves with a spool configuration selected as determined by a hazard identification / risk assessment for each and every application.
• The operation of the monitoring will now permit hydraulic power pack motors and pumps to remain online during operator access in to machinery areas which would have previously required full current isolation.
• The following installation guidelines would require the pump to be pressure compensated type or a relief / unloading valve fitted directly on pump outlet.

Installation

• The dual valve system has been designed to interface with new or existing hydraulic applications and can be fully interlocked in to any existing safety systems to a category 4 level of integrity
