The active pilot operated, 3-way high-response valves in cartridge design series TPQ are used in applications where high flow has to be precisely controlled at maximum dynamics. In this way they provide enhanced process accuracy and higher machine output. Typical applications are die cast, injection molding and hydraulic presses.
Markets:
• Industrial
• Molding
Benefits:
• Mounting pattern according to ISO 7368, cavity according to Parker house norm
• 6 sizes NG25 up to NG80 – fits almost all hydraulic systems
• Applicable for directional, speed, position, force and pressure controls – allows extremely variable use
• Very robust valve design – enables less downtime
• Closed-loop control of flows – enhanced process accuracy through high-precision production
• Fast step response – higher machine output thanks to shorter cycle times
• Short delivery time – no warehousing necessary
• Flow direction A to T and P to A
• Completely mounted adapted unit with integrated electronics
• Fail safe position in case of electrical and/or hydraulic power down
Applications:
• Suitable for general hydraulic applications
• Die cast
• Injection molding
• General presses
