CT5-060F-C-M-FW-B5-100

The CT5-060F-C-M-FW-B5-100 relief valve is built by Vickers within the Relief Valves series for hydraulic automation where remote electrical pressure control is needed. It employs a solenoid-controlled pilot-operated design, so an energized coil shifts the pilot stage while the main poppet modulates system pressure. The coil requires 6 V DC, permitting installation on mobile platforms that operate from low-voltage electrical supplies. Valve size 06 provides a flow capacity that fits medium-frame pumps and actuators without enlarging the manifold. A DG4V-3S pilot valve is integrated to direct oil from the pilot gallery to tank during opening events, improving stability at varying flows. The connection ports are cut for 3/4 in NPTF threads, allowing direct pipe mounting without additional adapters. A solenoid energize time of 30 ms gives rapid pressure release when commanded, while a maximum cycling rate of 3 Hz defines the highest repeatable switching frequency before thermal rise becomes excessive.

Electrical termination is handled by a housing tapped for a 1/2 in NPT conduit thread, letting installers route wiring through standard rigid metallic conduit for protection against vibration and fluid splash. Fluorocarbon (F3) seals are fitted to resist petroleum-based oils and maintain elasticity up to the rated service temperatures. The valve withstands pressures up to 210 bar, establishing the ceiling at which it diverts flow to prevent component damage. Reliable operation is specified between −20 °C and 68 °C, covering typical outdoor and factory environments without auxiliary heaters or coolers. A spring-centered arrangement repositions the pilot spool to neutral after the coil is de-energized, and the measured spring return time of 45 ms ensures consistent reseat delay that avoids pressure oscillation. These attributes combine to deliver a compact pressure-relief element whose wiring, sealing, and thermal limits suit automated hydraulic circuits subject to frequent duty cycles.
