Alfa laval SPC-2 control valves

SPC-2 - this is a sanitary valve with electropneumatic control for use in applications requiring precise control of pressure, flow, temperature, tank level, etc.

The principle of operation

The valve is remotely controlled by an electric signal and compressed air. The IP converter, which is an integral part of the drive, converts an electrical signal into a pneumatic one. The signal conversion is extremely insensitive to pressure surges. The pneumatic signal is transmitted to an integrated positioning device operating on the principle of a balance of forces, which ensures the position of the drive piston in direct proportion to the input signal. The signal level and the zero point are individually adjustable. The drive can be used for dual-band control using various calibrated springs.

Standard design

The valve consists of a valve body, etc
