Consolidated 2700 Series Safety Valve

Specifications

Valve Operation

• In Figure 1, the upper adjusting ring (G) is positioned to attain full lift at pop and to control the pressure at which the valve will begin to close. The lower adjusting ring (O) ensures a sharp pop action at the set pressure and cushions the valve on closing.
• When full lift is attained (Figure 2), the lift stop (M) rests against the yoke (T) to eliminate rapid opening and closing of the valve, adding stability to the valve. When the valve discharges in an open position, steam is bled into the chamber (H) through two bleed holes (J) in the roof of the disc holder. The steam escapes to the atmosphere through the pipe discharge connection (R).
