DCLR Electronic O Type Shut Off Ball Valves 1.6MPa 4MPa 6.4MPa Nominal Pressure
DCLR Electronic O-Type Shut-Off Ball Valve
The DCLR type electronic "O" type ball valve consists of an electronic actuator and a ball valve. It uses a power supply of 220V·AC, 50Hz, and includes a servo amplifier, a position signal generator, a handwheel mechanism, torque limit switches, travel switches, and a valve position indicator. It can accept 4-20mA·DC valve position feedback signals output by industrial control instruments or computers, etc. This valve features a simple structure, unlimited flow direction, low flow resistance, and large flow capacity. The valve seats are divided into two types: soft sealing and hard sealing. It is suitable for large-caliber and large-flow occasions.
