Gradual Flow Modulation: Unlike the B177 model, the T166 modulates flow by gradually opening as pressure builds up, ensuring a smooth and controlled bypass of excess capacity back to the supply tank. This process occurs silently, providing a quieter operation compared to other valves.

Bypass Protection: The T166 valve ensures safe operation by protecting the pump from overpressure situations, avoiding damage to the system or components.

Continuous Internal Bleed: It features a continuous internal bleed, which helps in eliminating vapors that may form within the system, maintaining pump efficiency and preventing vapor lock or cavitation.

Smooth and Silent Operation: The valve is engineered to operate quietly, making it a great choice for applications where noise reduction is important.
