Introducing Tectran's Proportioning Valve by Williams' Control
-Versatile Application: This three-way, compensating, pilot pressure-operated relay valve is highly versatile. It delivers an output pressure proportional to the amount of control pressure applied, making it suitable for various applications. Commonly used as tractor protection valves in Tractor-Trailer braking systems
-Brake System Protection: These relays play a crucial role in protecting the brake system pressure. The control signal is exhausted through the service treadle, preventing it from escaping downstream through an open service line
-Adjustable Ratio: The valve's adjustable output/control pressure ratio is a valuable feature. When installed on trucks or tractors, it allows for the balancing of trailer brake pressure with the tractor brake system
-Robust Ports: Equipped with (3) 1/4” NPT ports, ensuring reliable connections
-Adjustable Pressure Range: The outlet pressure to input pressure ratio is adjustable, ranging from 1.3:1 to 0.8:1, providing flexibility in various braking setups
-High-Quality Build: With a maximum operating pressure of 150 psi and an operating temperature range from -20°F to 200°F, this valve is built to withstand challenging conditions
-Cracking Pressure: The valve has a cracking pressure of 1.5 psi with a 100 psi supply, ensuring precise and responsive performance
Upgrade your braking system with Tectran's Proportioning Valve by Williams' Control, a versatile and reliable solution for maintaining control and safety in Tractor-Trailer setups.
