Ask A Question

Description & Features

Designed for mobile and industrial hydraulic circuits where manual flow control is needed during power loss events, the 3CP2 Series 2-Way 2-Position Pull-To-Open Manual Valve provides a reliable cartridge-style solution for controlled emergency actuation. A typical use case is lowering the boom on an access platform when hydraulic power is unavailable.

This cartridge-only valve features a 1.50 mm orifice with a rated flow of 4.00 GPM, allowing a small regulated flow to pass when the hand knob is pulled. Maximum operating pressure is 3,000 PSI, and the unit is rated for temperatures from -22°F to 194°F. Seals are Buna-N nitrile. The required housing uses cavity size A879 and the 3CP2 cartridge, both sold separately.

Filtration to cleanliness level BS5540/4 Class 18/13 or better is recommended. Suitable for harvesters, refuse haulers, and a range of mobile and industrial applications. Manufactured by Eaton Vickers, also marketed under the Danfoss Power Solutions brand. Catalog number C1MG46.

Question by: Steve P on Jan 1, 2026, 9:59 PM
got a manual pull valve on an access platform that’ll let me lower the boom if power drops out, is this the right kind of setup?
Answer by: Customer Support on Jan 3, 2026, 6:42 AM
On access platforms, a common use for the 3CP2 style cartridge is letting a small regulated flow pass when the hand knob is depressed, so you can lower a boom during a power failure.
Question by: Rick F on Apr 22, 2025, 6:09 AM
what's the typical setup for this valve on an access platform? trying to figure out if it'll work for lowering the boom when power goes out
Answer by: Customer Support on Apr 23, 2025, 6:58 PM
Pulling the hand knob is what gets this valve moving. When you depress or pull that knob, a small regulated flow passes through the 1.5 mm orifice, which gives you right around 4 GPM. That flow rate is exactly what makes it practical for controlled boom lowering during a power failure on an access platform. The cartridge fits a cavity size A879 housing, sold separately, so make sure you've got the right housing on hand before you go to install it.

What sort of applications would this manual valve be good for?
Answer by: Customer Support on Jul 14, 2025, 6:23 AM
A typical use would be on an access platform to lower the boom if the power goes out. You'll also find these on harvesters and refuse haulers, and in other mobile and industrial applications.
