Yoshitake MD-35R is an automated control diverting valve featuring a reduced bore and brass construction. Designed for cold and hot water as well as air applications, it offers smooth opening and closing to prevent fluid water hammer and ensure complete sealing. The valve features an outdoor, rainproof structure (IP65) and incorporates a space heater to prevent dew condensation, making it highly reliable across various environments.

Features

• Outdoor, rainproof structure (IP65 specified in JIS C 0920).
• Starts and stops are quick and accurate, and the indication of the working position can be checked.
• Smoothly opens and closes, preventing water hammer by the fluid and ensuring complete sealing.
• Manually operable.
• A space heater is incorporated to prevent dew condensation (0.5 W).
