Flow Meter Gas Sensus
Design features :
Temperature Compensation Element –
a design with increased strength to minimize deflection from valve drag,
the TCelement is more rugged and linear in movement, thus, more accurate in compensation.
Crank Bracket –
a simplified multipurpose design incorporating internal valve guides and index shaft support.
Fine tolerance, attained through precision molding, provides accurate positioning of the crank support.
Low friction polymer eliminates the need for lubrication.
Valve Seat –
close tolerances achieved through molded phenolic construction minimize
seat wear while providing a much smoother operation with a significantly lower differential.
Incorporates easily installed external valve guides.
Valve Cover and Links –
precision parts of engineered plastic materials reduce friction and are inert
to chemicals and condensates commonly found in gas lines.
Simple snap-on design with common left and right link reduces your parts inventory.
This design reduces the job of valve replacement.
Index Drive Shaft –
molded “dog” locks to brass index shaft eliminating “slop” often encountered in proving.
are made of tough, resilient cork and neoprene composition and the linear amount of gasket
is an absolute minimum due to “single-joint” design. This significantly reduces the chance of leakage.
Synthetic Rubber Glands –
in the cover stuffing box and in the valve plate to seal the flag rods assure positive
pressure sealing at these critical points.
The gland design produces pressure integrity with a minimum amount of drag.
One Piece Flag Rod –
closely controlled dimensions improve parallelism of all vertical segments.
Greater distance between bearing points has been designed to provide lateral stability.
Easy to position and install.
Molded Port & Pan –with Integral Diaphragm Stabilizers –
one piece construction of glass fiber reinforced material,
increases strength and eliminates a potential leak point.
Integral stabilizers provide positive positioning of the diaphragm assembly.
