TECHNICAL FEATURE
01. Dynamic sealing employs either V-ring seal assemblies suitable for high-speed, high-pressure applications or sliding ring seal assemblies with low friction coefficients suitable for low-speed, low-pressure applications.
02. The hydraulic cylinder is a double-acting, single-piston type, available in differential or equal-speed configurations, and may be optionally equipped with adjustable cushioning (using an adjustable flow control valve).
