Parker's manifold valve offers superior performance with a comprehensive range of remote and direct mount manifolds to suit all types of instrumentation installations, specifications and applications
Parker's remote and direct mount manifolds are
one of the most extensive in the process instrumentation industry
and accommodates all types of instrumentation installations,
specifications and applications. There is a choice of
single-isolate-and-vent, double-isolate-and-vent,
double-isolate-and-equalise, and
double-isolate-equalise-and-double-vent block configurations. All
needle valves in Parker’s H series manifold valves have PTFE seats
and gland packing as standard, with PEEK seats and graphoil gland
packing options.
The needle valves use a standard globe style bonnet design for safe,
reliable and repeatable performance. They feature an anti-blowout
stem, a self centering, non-rotating spindle tip and an externally
adjustable gland. As standard, the needle valves have metal-to-metal
seats to ensure 100% bubble-tight shut-off, and PTFE gland packing.
Graphoil gland packing and PEEK or PCTFE soft tips for gas
applications are available. Further options include anti-tamper
spindles, as well as lockable handwheels and T-bars.
Most of the valves and manifolds in this series are manufactured
from 316 stainless steel. Oxygen clean, NACE compliant and other
types of materials are also available. As standard, the components
have a maximum working pressure of 10000 PSI (689 bar). The
operating temperature range depends on the type of valve seat and
gland packing material that is specified.
