Material: The valve body is typically made of high - strength alloy steel or durable cast iron. This material provides excellent resistance to high - pressure forces and corrosion. The surface may be treated to enhance its resistance to wear and environmental factors.
Dimensions: The size of the valve body is designed to fit into the hydraulic system's layout of the PC200 - 8. The overall length can range from [X] mm to [Y] mm, the width from [A] mm to [B] mm, and the height from [C] mm to [D] mm. It includes connection ports for the hydraulic lines, which are usually threaded with standard sizes to ensure a proper seal and connection.
Internal Components
Spool: The spool is a precision - machined component that controls the flow of hydraulic fluid within the valve. It is made of hardened steel or a wear - resistant alloy. The spool's diameter can range from [E] mm to [F] mm, and its length from [G] mm to [H] mm. The surface finish of the spool is crucial for smooth operation and minimal leakage.
Springs: The valve contains springs that exert a force on the spool to maintain the normal operating position and determine the cracking pressure (the pressure at which the valve begins to open). The springs are made of high - quality spring steel with specific spring constants. The wire diameter of the springs can range from [I] mm to [J] mm, and the free length from [K] mm to [L] mm.
