DESCRIPTION
The ABAC Monoflange Valve provides a safe, simple and economical method for the direct installation of pressure instruments with a flanged connection to the process. Combines in a single unit mechanized on a flange the effects of blocking and bleeding, essential for the correct assembly of manometers, pressure switches, transmitters and pressure indicators. Its design offers a more compact installation, with less possibility of losses and substantial savings, both in assembly labor and in the acquisition cost.
FEATURES
• Threaded bonnet for blocking and bleed effects. Of the "dry thread" system, which keeps the stem thread isolated from the process fluid.
• Back seated stem to prevent blow out risk and to isolate the packing from the process fluid.
• Non-rotating tip.
• Bonnet lock pin to prevent accidental disassembly.
• Made of AISI 316 stainless steel.
• Compatible with ASME B16.5 flanges from 1/2" to 2" (DN 15 to DN 50).
• Class RF150 to Class RF1500, up to 2" nominal size.
• NPT F connection for Instrument and Vent.
• Block, block and bleed, and double block and bleed versions.
