DN15 - DN250 Different Pressure Balancing Valve
The Series SDP Differential Pressure Balancing Valve is designed to keep constant differential pressure across the supply pipes and return pipes, control valve or terminal unit in air-conditioning or heating system. It avoids hydronic disturbances resulting from variations in system differential pressure.
Features:
Self-acting differential pressure conrol, no external power needed
On-site setting of differential pressure
Wide controllable range of differential pressure
Handwheel equipped with differential pressure indicator
Equipped with measuring points and air vent
Equipped with three-way measuring connector
