Double Block And Bleed Plug Valve
Product Size: 2 "-24"
Pressure rating: 150LB-1500LB
Design standards: ASME B16.34p, ASME B16.34
1. During the opening and closing process of the valve, there is no contact between the sealing surface of the valve body and the sealing surface of the sliding plate. Therefore, the sealing surface has no friction or wear, and the valve has a long service life and low switching torque;
2. When repairing a valve, it is not necessary to remove the valve from the pipeline. Simply remove the valve bottom cover and replace it with a pair of sliding blades, making maintenance very convenient;
3. The inner cavity of the valve body is plated with hard chromium, and the sealing area is hard and smooth;
4. The valve has an automatic relief device (optional), which prevents abnormal pressure increase in the valve chamber and verifies the effectiveness of the valve after it is completely closed;
5. The valve switch indicator is synchronized with the switch position, which can accurately display the opening and closing status of the valve.
