The document details the specifications for the ZA 6 RE series of pilot-operated check valves, including models ZA 6 RE-A, ZA 6 RE-B, and ZA 6 RE-AB. Key specifications include a maximum working pressure of 320 bar, a maximum flow rate of 40 l/min, fluid temperature range from 0°C to 75°C, ambient temperature range from -25°C to +60°C, and a weight of 1 kg.
The valves include components such as O-rings and back-up rings, with specific dimensions and materials like NBR 90 Shore. The document also mentions the use of Viton® fluoroelastomers for certain sealings.
Performance curves are provided, showing values determined at an oil viscosity of 24 cSt and an oil temperature of 50°C. The document specifies the pilot ratio as 1:4 and provides options for minimum opening pressures of 1 bar and 5 bar.
Examples of applications and sectional drawings with seal kits are included, illustrating the valve's effectiveness in different lines (A, B, AB) and highlighting the sealing surfaces.
