High-precision control valves for gases and liquids

Product catalog summary

Overview: The M-Flow high-precision control valves are designed for precise adjustment of gases and liquids. They feature tightly closing needle valves and are available with various rotary knobs, including options for anodized aluminum or stainless steel bodies.

Specifications: The valves are available in two sizes, M-Flow 25 and M-Flow 35, with connections of G 1/4" and G 1/2" respectively. They are constructed with anodized aluminum or stainless steel 1.4305 and use sealing materials such as FKM, EPDM, or FFKM. The valves can withstand a maximum pressure of 40 bar and operate within a temperature range of -40 °C to 100 °C.

Design and Features: The valves have a compact, modular construction and can be configured as straight valves or valve cartridges for custom integration. They offer precise adjustment with a 15-turn micro valve and non-rotating valve needles for stable settings. Four knob variants are available, including a Digiturn knob with a 100-division display.

Performance: Each valve is tested for a leak rate of less than 1 x 10-5 mbar l/s He. Different Kv-values are available for optimal control ranges, and custom solutions are offered for specific customer needs.

Dimensions: Detailed dimensions are provided for both M-Flow 25 and M-Flow 35, including various knob options.

Type Code: The document includes a type code system for specifying instrument type, size, materials, setup, valve direction, process connection, valve size, and options.
