CHECK VALVE WITH SOFT OR METAL SEALING

Product catalog summary

General Specifications
Type 6140 check valve is available in dimensions ranging from DN 40 to DN 400, with pressure ratings of PN 10, PN 16, and PN 25. The valve is constructed from steel or stainless steel, with seat materials including NBR, EPDM, FPM, and metal/metal, each with specific maximum temperature ratings. Flange connections match the pressure ratings.

Options
Optional features include dimensions up to DN 600, pressure rating up to PN 40, and materials such as aluminum, aluminum bronze, or brass. Flanges can have grooves in the bearing surface, with flange connections available in PN 6 and PN 40.

Material Description
The valve features a reliable and simple construction, self-aligning flanges, and a flexible, lightweight design. It is easy to mount due to the eye bolt on top and offers a large field of application with various options. The disc and hinge are cast as one, and the protected O-ring is placed in the body to prevent flow, detachment, and tear.

Dimensions and Performance
The document provides detailed dimensions and performance data for each valve size, including weight and kv-value. For example, a DN 40 valve weighs 0.8 kg with a kv-value of 17.2 m³/h.

Opening Pressure and Pressure Drop
The opening pressure varies with the degree of valve opening and size, with specific values provided for different dimensions. A pressure drop diagram is included, showing the relationship between pressure drop and water flow at 15°C. The document provides a formula to calculate equivalent water flow for fluids other than water.
