Multiquip 34585 Four Way Valve Assembly

The Multiquip 34585 Four Way Valve Assembly is a genuine OEM component designed for Essick and Whiteman stationary and portable mixer models, including the EM120P Series, EM120S Series, WM120PH, WM120SH, PRO20, PRO12, PRO12E51, and PRO12E53. As an authentic Multiquip OEM part, the 34585 is manufactured to the same standards as the original, ensuring a direct, trouble-free installation without the guesswork of an unverified substitute. If your mixer is losing hydraulic or air pressure control, cycling inconsistently, or failing to shift between functions, this valve assembly is a critical component to inspect and replace.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring correct porting geometry and sealing integrity specific to this four-way valve application.
• Direct-Fit Replacement — Engineered to drop into the existing valve mounting position on compatible mixers, with matching port configuration and connection points for straightforward installation.
• Broad Mixer Compatibility — Confirmed fitment across EM120P Series, EM120S Series, WM120PH, WM120SH, PRO20, PRO12, PRO12E51, and PRO12E53 mixer models.
• Consistent Flow Switching — A properly functioning four-way valve ensures clean, responsive directional control, keeping the mixer's hydraulic or pneumatic circuit performing as intended through full working cycles.
• Pressure and Leak Integrity — OEM-grade internal seals and valve body tolerances are matched to the system's operating pressure range, helping prevent bypass leakage that can degrade mixing performance over time.

The four-way valve assembly controls the directional flow of hydraulic or pneumatic fluid within the mixer's operating circuit, routing pressure to the correct actuators depending on the machine's cycle position. It acts as the switching hub that tells the system which direction to move — without it functioning correctly, the mixer may stall mid-cycle, fail to reverse, or lose consistent drum or paddle control. A worn or failed valve typically presents as sluggish response, uncontrolled cycling, or an inability to hold position under load.
