DOUBLE-SEATED GLOBE - SERIES 20

The double-seated plug is inherently balanced, enabling economic actuation of larger valves. The Series 20 is ideal for medium and low-pressure applications, where tight shut off is not essential. For high-capacity applications with high pressure drops, the valve can be fitted with a High Friction (HF) style trim.

Why Choose a Series 20 Valve?

• High flow capacity.
• Minimum differential plug areas to reduce actuator force requirements.
• Excellent flow control rangeability.
• Cast body proportioned to withstand high pipe stresses without distortion.

Features:

• Top and bottom guided.
• Trim options: Contoured, HF, low noise, anti-cavitation.
• Low unbalance area for each valve size.

Trim Designs

• Contoured trim: Used in the majority of applications, this trim is most suited to low pressure-drop applications. The contoured plug has a specially profiled plug head, which offers a smooth profile to the flow and permits a high pressure recovery.
• High Friction high-capacity trim: Developed for higher pressure-drop applications where high capacity flows are required. High Friction (HF) style extended seat rings ensure low pressure recoveries. This trim is ideal for preventing the onset of cavitation and reducing noise levels from liquid or gas flows.
