The Greenlee PVA0022 Block Unit is a high-pressure hydraulic control valve engineered to provide reliable flow control for compatible cutting and crimping tools. Designed with a compact 4-way, 3-position valve, this unit enables controlled advance, retract, and hold functions, allowing operators to maintain precise positioning during hydraulic tool operation.

The PVA0022 can be mounted directly to the tool or connected remotely using hydraulic hoses, giving operators flexibility in how the system is configured for different work environments. Its built-in hold function allows the tool to maintain position when the control lever returns to neutral, helping improve operational control and efficiency.

Engineered for demanding hydraulic applications, the unit features a high-pressure design with a return line ground-dump safety valve set between 3,000 and 4,000 PSI (207–275 bar) to protect the system during operation. The valve is compatible with double-acting hydraulic tools and can also be used with certain single-acting tools, providing greater versatility across tool setups.

With its compact design, durable construction, and precise hydraulic control, the Greenlee PVA0022 Block Unit is an essential accessory for professionals who need dependable performance and improved control when operating hydraulic cutting or crimping equipment in the field.
