AGI™ Series H70DB Primary Root Valves

Features

• Elimination of up to 80% of leak points produced by traditional 'piped-up' instrumentation penetrations increases operator and facility safety.
• Reduced cost of ownership through reduction of necessary components.
• Single-piece barstock construction and pre-installed bleed valve provide maximum strength and rigidity and eliminate requirement for fittings, tees, valves and tubing.
• Fast installation reduces costs: valve is shipped complete and hydrostatically tested for immediate, hassle-free installation.
• Compact design requires minimum space for operation and installation.
• Replaceable soft or metal seats can be removed and replaced easily in-line eliminating the need for valve removal.
• Non-rotating stem design eliminates packing wear and seat galling, extending valve life.
• Provides assured reliability in severe service applications.
• Metal-to-metal body-to-bonnet seal in constant compression prevents bonnet thread corrosion, eliminates possible tensile breakage and gives a reliable seal point.
• Safety back seating prevents stem blowout or accidental removal while in operation and provides a metal-to-metal secondary stem seal while in the full open position.
• Bonnet lock plate prevents accidental separation of bonnet from body while allowing easy maintenance and repair.
• Optional multi-port gauge connections allow versatile positioning of gauges or pressure switches without additional penetration of the main piping.
