Design Specifications:

• Three (3) valves in one (1). A triple duty valve replaces a balance valve, shut-off valve and check valve.
• Valves are complete with FF flanges in accordance with ASME B16.1
• Automatic and silent operation. The valve is spring loaded to ensure that the disc closes as the line flow approaches zero. This feature prevents water hammer.
• Line pressures of approximately 1/4 psi will open the disc.
• Flow through the valve can be adjusted from zero to full flow by the ACME rising stem.
• Soft-seated dovetail o-ring groove ensures bubble-tight sealing when the valve is positioned in the fully closed position.
• The rising stem incorporates a graduated position indicator to ensure accurate disc positioning for throttling service.
• All valves supplied with hand-wheel for ease of operation.
• Drain and differential connections are furnished with a plug as standard.
