» Left And Right Swing Valve Cylinder
Product Description:
The swing valve cylinder of the pump truck (also known as the S-valve swing cylinder, directional cylinder,
or distribution valve cylinder) is a key hydraulic actuator that controls the left and right switching of the concrete distribution valve (usually the S-valve or gate valve). Its function is to accurately, quickly, and reliably drive the swing of the distribution valve, so that the outlet of the concrete conveying cylinder alternately connects with the conveying pipeline, achieving continuous pumping of concrete.
Specification Parameters
Function
Drive the distribution valve swing accurately, quickly, and reliably
Cylinder Diameter
180mm -280mm
Stroke
2000mm -2300mm
Thrust
300 kN -800 kN+
Rod Diameter
110mm -180mm
Working Pressure
28 MPa -35 MPa+
Main Features
Double acting oil cylinder: alternate oil inlet/outlet on both sides of the piston, driving the piston rod to reciprocate (extend/retract), corresponding to the left and right swing of the S valve, respectively.
Short stroke, high-frequency commutation: The stroke is short (usually 200-300mm), but the commutation frequency is extremely high (up to ten or even dozens of times per minute), requiring fast response speed, smooth commutation, and no impact.
Accurate position control: It is necessary to accurately stop at the end positions at both ends (left and right swing positions), ensuring that the S valve port is completely aligned with the outlet of the conveying cylinder to avoid leakage or jamming. Mechanical limit or hydraulic buffering is often used.
Excellent sealing performance: Dynamic sealing (piston rod sealing) is crucial, as it must be able to withstand high pressure, high-frequency motion, and have minimal leakage. Internal leakage can cause slow and weak valve switching, while external leakage can pollute the environment and waste hydraulic oil.
Compact structure: usually installed near the valve group of the pumping system, with limited space, requiring a compact structure.
Connection method: The cylinder bottom and rod end are usually connected to the valve group swing arm or drive mechanism through earrings, forks, or pin shafts.
Our construction machinery hydraulic cylinder is a heavy-duty actuator designed to convert hydraulic energy into linear motion and force, powering the essential movements of construction equipment. These cylinders are widely used in machinery such as excavators, loaders, bulldozers, cranes, and concrete trucks to perform functions like lifting, pushing, steering, and digging. Built to withstand high pressure, heavy loads, and harsh working environments, construction machinery hydraulic cylinders are manufactured with robust materials, precision seals, and advanced surface treatments to ensure strength, durability, and long service life. They play a critical role in ensuring efficiency, safety, and reliability in construction operations.
