Frequently Asked Questions
Wafer type valves are sandwiched between two flanges, resulting in a much thinner profile and lower weight compared to lug or flanged types, which reduces installation costs and space requirements.
EPDM is ideal for water and steam applications, whereas Viton is recommended for high-temperature environments and aggressive chemicals or oils.
Yes, by selecting the Stainless Steel (CF8/CF8M) disc and stem options, the valve provides excellent resistance to corrosion in chemical processes.
Ductile Iron (ASTM A536) offers significantly higher strength and flexibility than Cast Iron (ASTM A126), making it better suited for higher pressure and impact loads.
The short neck is specifically designed for tight installation areas where vertical clearance is limited, allowing the valve to fit into narrow spaces.
Yes, the Model 15 design supports various actuation methods, including pneumatic and electric actuators, depending on the stem configuration.
