Proportional Throttle Valve with Shut-Off Valve - Series TEA TEA080EW09A2NLWJ

With flow rates up to 9500 l/min and fast response times, proportional throttle valves series TEA are predestined for injection molding and die cast applications. The directional valve integrated in the pilot circuit provides the safety function.

Parker's proportional throttle valves in cartridge design with shut-off valve series TEA combine high flow and fast response times and thus provide high efficiency. These accumulator discharge valves are preferably used in hydraulic systems where high flow rates are discharged from hydraulic accumulators over a short operating period (in the range of milliseconds).

Typical applications are injection molding and die cast machines as well as hydraulic presses. Basically the function of an accumulator discharge valve corresponds to the function of a TDA throttle valve. In addition a directional valve is integrated in the pilot circuit to meet the relevant safety regulations.

Markets:
• Industrial
• Molding

Features/Benefits:
• Cavity and mounting pattern according to ISO 7368 - for quick, easy integration
• Maximum operating pressure up to 350 bar - suitable for demanding hydraulic applications
• High flow rates up to 9500 l/min - enables efficient operation
• Various sizes, NG25 - NG100 - allows extremely variable use
• Short delivery time for most sizes - no warehousing necessary

Applications:
• General presses
• Injection molding
• Die cast

Safety function:
The directional valve provides the safety function. When the solenoid is deenergized and the spring is in end position, pilot pressure from X presses the control piston into lower end position and the main poppet is closed. As a result the flow from B to A or from the reservoir system to the machine is blocked.
