G Thread Double Pilot Hydraulic Lock with Vrde-G Series Connection

The VRDE-G series G thread hydraulic lock uses ISO 228-1 parallel pipe threads: G1/4 (19 TPI), G3/8 (19 TPI), and G1/2 (14 TPI). All ports are female-threaded with flat sealing faces for bonded washers. This thread connection hydraulic valve ensures leak-free integration with European standard hydraulic lock manifolds and hose assemblies without adapters.

This double pilot operated check valve controls flow in both cylinder directions simultaneously, enabling bidirectional load holding and controlled lowering. Single pilot valves only lock one port. Choose the VRDE-G dual flow control lock valve when your circuit requires retention on both rod and cap sides, such as in outrigger or boom cylinders.

No. The VRDE-G hydraulic lock valve G port is strictly parallel (non-tapered). NPT and BSP tapered threads will not seal properly and may damage the valve body. Always verify your mating port is ISO 228 G-series before installation. Use DIN 3869 bonded seals for reliable thread connection hydraulic valve sealing.

The VRDE-G series European standard hydraulic lock is ideal for equipment built to CETOP/ISO standards: mobile cranes, aerial work platforms, agricultural machinery, and industrial presses using G-thread plumbing. Its double pilot check valve design provides cost-effective load holding without requiring metric-to-imperial adapters in legacy European standard hydraulic lock systems.

Yes. The VRDE-G dual flow control lock valve features hardened steel poppets and guided seats rated for 350 bar continuous / 420 bar peak. Shock absorption damping orifices prevent chatter during rapid load reversals, ensuring stable bidirectional hydraulic lock performance in demanding mobile equipment duty cycles.
