Standard Composition of Valve
The document outlines the specifications for GE Series hydraulic valves, specifically shuttle valves made from carbon steel. These valves are 3-way types available in sizes ranging from DN6 to DN25, with end connections including BSP, NPT, and SAE. They can withstand pressures up to PN500 and operate within a temperature range of -20°C to +100°C. The valves are galvanized for treatment.

Specifications
- Type: Shuttle valve 3-way
- Sizes: DN6 to DN25
- Ends: BSP, NPT, SAE
- Pressure: Up to PN500
- Temperature Range: -20°C to +100°C

Material Composition
The valves are primarily composed of carbon steel, specifically material 1.0737 for the body and adapter, and UNl3545 for the ball.

Valve Options and Customization
The document mentions the availability of reduced bore options, special threads, and pressure classes up to PN25 Mpa upon request. Customers are advised to consult the technical/commercial service for special requests.

Dimensional Specifications
Detailed dimensions are provided for various valve types and sizes, including GEV DIN/ISO 228 BSP and GEV ANSI/ASME B1.20.1 NPT. The dimensions cover parameters such as nominal dimension (DN), pressure (PN), and various physical dimensions (A, B, D, G, ØM, P, Q, ØR, ØLW) along with weight.

Pressure Drop Curves
The document includes pressure drop curves for different valve sizes (VU2P 1/4", VU2P 3/8", VU2P 1/2", VU2P 3/4", VU2P 1") showing the relationship between flow rate (Q in l/min) and pressure drop (Δp in bar). These curves help in understanding the flow characteristics and performance of the valves under different conditions.

Important Notes
The company reserves the right to make dimensional changes without prior notice, emphasizing the need for customers to verify specifications before purchase.
