Product Category: Hydraulic Valves and Additionals
Brand Compatibility: Parker (including MV400s series), Bosch Rexroth, and other leading hydraulic component manufacturers used in Schwing concrete pumps
Product Description:
Hydraulic valves and related components are vital for the precise control of fluid power in Schwing concrete pumps. These components regulate the flow direction, pressure, and volume of hydraulic fluid throughout the system, enabling smooth operation of key functions such as pumping, boom movement, hopper agitation, and outrigger deployment.
"Additionals" refers to complementary components like sensors, pressure switches, and control units that integrate with the hydraulic valves to monitor, control, and optimize system performance.
Key Features:
-
Precise Flow and Direction Control:
Directional control valves (DCVs) guide fluid to the appropriate actuators, enabling boom movement, cylinder extension/retraction, and more.
-
Pressure Management:
Includes pressure relief, reducing, and sequence valves that maintain safe and efficient pressure levels throughout the system.
-
Durable Construction:
Built from high-grade materials to endure the high pressure and abrasive environment of concrete pump operation.
-
Multiple Actuation Types:
-
Manual: Lever- or knob-operated
-
Solenoid: Electrically actuated
-
Hydraulic (Pilot): Controlled via fluid pressure
-
Pneumatic: Controlled by compressed air
-
Sealed & Leak-Resistant:
Designed with high-integrity seals to minimize fluid loss and contamination.
-
Modular Design:
Allows for flexible configuration and simplified maintenance or expansion of valve assemblies.
Common Applications in Schwing Concrete Pumps:
-
Directing fluid to main pumping cylinders
-
Operating hopper agitator motors
-
Managing boom slewing, lifting, and extension
-
Deploying and retracting outriggers
-
Maintaining system pressure balance and safety
-
Enabling remote or automated function control
Component Types (Visual Identification & Function):
-
Solenoid Valves: Electrically controlled valves for directional and flow control
-
Manual Valves: Hand-operated for localized control
-
Pressure Sensors & Switches: Provide monitoring or signal when set pressure levels are reached
-
Modular Valve Blocks: Stackable units that streamline multiple hydraulic functions
-
Poppet & Relief Valves: Maintain pressure limits and allow flow in one direction
-
Spool Valves: Direct flow through multiple channels using a sliding spool
-
Pilot-Operated Valves: Enable low-effort control of large-volume flow paths
Example – Parker MV400s Series:
Some valves may belong to the Parker MV400s series, a range of modular directional control valves specifically engineered for mobile equipment. These are commonly used in Schwing pumps due to their rugged design, high flow capacity, and configuration flexibility.
Fitment & Identification Tips:
To ensure correct selection and compatibility:
-
Confirm your Schwing pump’s model and serial number
-
Reference the official Schwing parts manual or consult a certified parts provider
-
Check for model numbers or identification tags on the valve or component
-
Note the hydraulic circuit or function the valve is part of (e.g., boom, outrigger, main pump)
Important Note:
Using the correct hydraulic valve or sensor is crucial for maintaining safe, efficient operation of your Schwing concrete pump. Incorrect or incompatible components can lead to performance loss, system damage, or operator safety risks.
