• Product Overview

Pilot-Operated Micro Pressure Regulator, it does not require external energy (power supply, air source) and directly uses the energy of the controlled medium for automatic control and operation. The pressure is set on the controller by adjusting the spring and can be set continuously while the valve is in operation. Pressure reduction ratio ≤4000:1, high control accuracy, rapid response, good sealing performance.

Performance Characteristics

• The ZPL620 pilot-operated micro pressure regulator does not require external energy and uses the energy of the medium to be regulated as the power source to achieve automatic regulation. This product adopts a single-seat valve fast-opening flow characteristic regulation mechanism, with stable medium pressure, high regulation accuracy, safe and reliable sealing performance, and the set value can be adjusted arbitrarily during operation. Therefore, it is suitable for various industrial furnace combustion system fuel gas, petroleum products or oil tank protection gas (nitrogen sealing) and heat treatment protection gas micro-pressure automatic regulation occasions.
• 1. No external driving energy is required, and the equipment cost is low.
• 2. No filler, no friction active components, sensitive adjustment, high control accuracy.
• 3. The set point is adjustable and has a wide range, which is convenient for users to adjust continuously.
• 4. The pressure reduction ratio is particularly large, for example, 0.8MPa before the valve, 50Pa after the valve, and the pressure difference ratio reaches 1600.
