The Yuken MSW-01-X-30 Modular Throttle and Check Valve is a highly versatile hydraulic component used to achieve precise speed control of hydraulic actuators within industrial circuits. Its modular, stackable design eliminates the need for complex external tubing and fittings, reducing potential leak points and simplifying system layout.
Key features and specifications:
Functionality: The valve provides a throttle mechanism that restricts fluid flow in a controlled direction (e.g., meter-out flow from a cylinder) to regulate speed. Simultaneously, an integrated check valve allows for unrestricted free flow in the reverse direction.
Configuration: The “X” in the model code typically denotes control over both the A and B ports. Adjustment is made using a calibrated knob that is pressure-balanced for easier adjustment even at high operating pressures.
Performance:
Max. Operating Pressure: Up to 315 bar (4,570 psi).
Max. Flow Rate: Can handle flow rates up to approximately 60-80 L/min.
Construction: The valve body is made from high-strength materials, typically cast iron or high-strength steel, suitable for use with standard mineral hydraulic oils.
Application: It is typically used in circuits where the line pressure is relatively steady and precise speed regulation is required.
This valve’s compact structure and performance make it a reliable solution for various applications where space is a constraint, such as automated machinery and mobile equipment.

Stackable Throttle Cum Check Valve MSW-01-X-30 By YUKEN
The Yuken MSW-01-X-30 is a compact, NG6 (CETOP 3/ISO 4401-03) size modular throttle and check valve. It functions as an adjustable needle valve flow restrictor in one direction (port ‘A’ or ‘B’ depending on specific configuration) and permits unrestricted free flow in the opposite direction via an integrated check valve. Constructed from durable cast iron or steel, this sandwich-style valve handles working pressures up to 315 bar. The “X” in the model number typically indicates flow control on both A and B ports in a “meter-out” configuration. It is designed to minimize piping and save space in hydraulic power units.
