Description
The Copeland 065621 (model 200RB3T4M) is a heavy-duty, pilot operated refrigeration solenoid valve engineered for reliable flow control in commercial and industrial refrigeration systems. Featuring a 2-way, normally closed design, this valve body remains closed when de-energized, providing a safe default state that protects your system during power interruptions. The manual stem override allows technicians to open the valve manually for servicing, commissioning, or emergency operation without energizing the coil.
