FAQ

How do S7500/S7700 Series 3-piece ball valves operate?

This series of ball valves uses a 3-piece body construction to control flow paths. The ball rotates against the sealing surfaces of the seats to open or close, providing rapid control of high-purity media and zero-leakage sealing.

How should the S7500/S7700 be compared for technical selection?

When selecting a valve, consider the size range (½-4"), CF3M body material, temperature range (-46°C to 232°C), maximum operating pressure of 1000psi WOG, available seat materials, and zero-leakage rating. The specific configuration should be confirmed based on the actual media, temperature, and pressure conditions.

What are the main applications for this ball valve series?

Suitable for high-purity processing, aseptic, semiconductor, food, and beverage applications with stringent hygiene and material compatibility requirements.

What end connection options are available, and how should they be selected?

End connections include quick clamps, extended tube ends, and SAE male connections. Selection should be based on the system piping interface standard and installation space to ensure secure sealing and ease of installation.

What sealing material options are available?

The standard seal is PTFE, with optional TF M 1600, UHMWPE, or cavity fillers to meet media corrosion resistance requirements and temperature conditions. The specific selection should be confirmed based on actual operating conditions.
