Piston Type Digital Control Valve
Product Range
Piston Type Digital Control Valve
Flow-Tek Piston Type Digital Control Valve is an electrically actuated, hydraulically operated multi-functional control valve designed for precise and reliable performance.
Widely used in loading terminal automation systems at refineries and petroleum storage facilities, this valve ensures precise and efficient filling of road tankers and railway wagons.It is equipped with two solenoid valves that receive signals from batch controllers, enabling automatic positioning for low, medium, or high flow rates as per programmed requirements.
Features
- Pilot-operated valve based on a balanced piston principle for stable and accurate performance.
- Spring-biased to the closed position for enhanced safety and controlled operation.
- Opens automatically when line pressure differential overcomes spring force.
- Pilot controls regulate pressure on the piston spring side for precise positioning.
- Designed for accurate flow rate control and batch delivery when integrated with electronic batch controllers.
- Supports low-flow startup, high-flow operation, low-flow shutdown, and final tight shut-off.
- Maintains consistent flow rates despite fluctuations in line pressure, improving flowmeter accuracy.
- Model BV88 includes an external pilot control loop for enhanced operational control.
- Equipped with normally-open and normally-closed solenoid pilots for programmed flow sequencing.
- Integrated strainer and adjustable opening/closing speed controls for smooth valve operation.
