The Burner-Ready Advantage
The standout feature of the 119EZ and 119EZS models is the integrated opening speed controller. In burner applications, if a valve snaps open too quickly, the sudden rush of fuel can lead to hard starts or failed ignitions.
-
Tuned Ignition: Technicians can adjust the opening speed to match the specific draft characteristics of the burner, ensuring a smooth, safe light-off sequence for the main burner.
-
119EZ vs. 119EZS: The S in 119EZS typically denotes a specialized construction (such as internal materials) suited for specific environmental or pressure requirements, though both share the same fundamental speed-control architecture.
핵심 기술적 특징
-
Quick and Easy Leak Detection: The design includes a 1/8-inch NPT tapped vent in the spring case. This allows for easy piping to a remote location or the installation of a visual leak indicator, ensuring any diaphragm failure is detected immediately.
-
Simple Spring Adjustment: Changing the set point or switching pressure is straightforward. By removing the closing cap and turning the adjustment screw, you can compress or relax the internal spring to meet the exact pressure needs of your process.
-
Low Leakage Performance: The valves utilize a soft-seat design (typically Nitrile or similar elastomers). This ensures a tight, bubble-tight shutoff when the valve is in the closed position, preventing fuel wastage and increasing site safety.
