Specifications
The document details the GE Series CS Hydraulic Valves, specifically the Direct Acting Relief Valve with Manifold. These valves are made from carbon steel and are available in sizes DN6 to DN10. They feature BSP, NPT, and SAE ends and can handle pressures up to PN350. The operational temperature range is from -20°C to +80°C, and the valves are galvanized for protection.

Structure
The valves are categorized by type and connection ends, including GAS DIN/ISO 228 BSP, NPT ANSI/ASME B1.20.1, and SAE J1926-1. The material used is carbon steel. The valves have a maximum flow rate of 40 L/min and are compatible with fluid viscosities as per ISO 3448. Filtration follows ISO4406 standards, and the fluid temperature range is -20°C to 80°C, with ambient temperatures from -20°C to 50°C. Standard seals are made from NBR 70 Shore A, with optional Viton seals available.

Performance
The valves are designed to operate within a setting range of 10-180 bar, with a standard setting at 5 L/min of 90 bar. Adjustment options include a screw with a steel cap, tamper-resistant cap, and handknob with locknut, with specific ranges available on request.
