Monoflange - Block & Bleed Valves
Monoflange Process to Instrument Valve
Parker's Monoflange is designed to replace conventional
multiple-valve installations currently in use for interface with pressure
measuring systems in process control applications.
Product Overview
By combining customer-specified valves into a single
manifold valve, Parker’s monoflange significantly reduces the number of
potential leak paths. The monoflanges also have a lower system mass, which
reduces loading and vibration stresses, further improving safety and
reliability. The Parker Monoflange has needle valve primary and secondary
rather than ball valves. The monoflange is preferred by some operators as it is
smaller than a traditonal double block and bleed valve, giving even more space
and weight advantages. This ensures that the monoflange is it is a cost
efficient option for owner / operators.
The monoflange allows the mounting options to suit whether the pipeline is vertical or horizontal, the gauge or pressure transmitter can be fitted on either the front face or on the outer diameter of the body to allow good orientation and ease of reading.
Parker’s monoflange is available in a wide range of single-,
two- and three-valve configurations, including block, double-block,
block-and-bleed, double-block-and-bleed and block-bleed-block. Standard flange
sizes include 1/2", 3/4", 1”, 1-1/2” and 2”, together with API and
DIN standard versions, and there is a extensive choice of flange classes, from
ANSI 150 to 2500. Standard outlet vents are 1/2" female NPT. Depending on
monoflange size and configuration, other options include 1/4", 3/8”, 6 mm,
10 mm and 12 mm sizes, and male NPT or Parker inverted A-LOK™ double ferrule
compression fittings.
