The SD14Q-OT Pneumatic Monoblock Valve is engineered for precision control in demanding environments. Featuring a robust monoblock structure (Section 162), this 1-spool valve is operated via a pneumatic control method, allowing for seamless integration into air-assisted hydraulic systems. With a substantial rated flow of 120 L/min (31.7 US gpm) and a maximum operating pressure of 315 bar (4600 psi), it ensures reliable power delivery for heavy machinery. The valve utilizes standard G3/4 inlet and outlet ports for easy connectivity. Its wide operating temperature range (-40°C to +60°C) and viscosity tolerance (15-75 cSt) make it ideal for extreme outdoor conditions found in construction, agriculture, and material handling. Key advantages include its compact space-saving design, high durability against pressure spikes, and sensitive pneumatic response for smooth operation of cylinders and motors. It is widely applied in tractors, loaders, and various industrial mobile vehicles.
