Valve Manifold Panel
An open, wall-mounted four-stick UHP gas distribution panel that divides one compatible central supply into independently regulated and isolated process-tool branches without the footprint of an exhausted enclosure.
- Four modular pressure-controlled outlet sticks on one open backplate
- Independent branch isolation for service without a common shutdown
- Electropolished 316L flow path with selectable purge and control circuits
Produkteinführung
The Valve Manifold Panel is an exposed secondary distribution assembly for compatible inert or otherwise facility-approved high-purity gases. The selected catalogue configuration places one common inlet header and four parallel gas sticks on a rigid stainless mounting plate. Each stick has a compact pressure regulator, local pressure gauge, upstream and downstream diaphragm isolation valves, and one dedicated tool outlet. A compact controller above the backplate can supervise a normally closed common inlet valve and four branch shutdown signals. The open architecture gives technicians direct visual and service access where an exhausted containment box is not required by the gas hazard assessment. It has no cylinder, pigtail, cabinet or door and is distinct from a single-source pressure panel, an enclosed valve manifold box and a bare unregulated pipe manifold.
Key Features
A dedicated regulator and gauge on each stick support different downstream delivery-pressure settings
Upstream and downstream diaphragm valves isolate one branch while the other qualified outlets remain available
Open component access shortens inspection, adjustment and planned replacement work in approved service areas
Electropolished 316L tubing and low-dead-volume diaphragm components help protect UHP gas cleanliness
A horizontal inlet header and aligned outlet interfaces simplify routing and permanent branch identification
Optional purge and evacuation circuits allow trapped branch volume to be displaced before maintenance
Modular stick spacing supports future branch population, component changes and gas-specific material selection
Optional common and stick-level normally closed valves provide defined automatic isolation points
The panel can be configured for manual, semi-automatic or monitored distribution without changing its open identity
Kunden Produktbedenken
An open valve manifold panel must match the gas hazard, preserve branch purity and make each pressure-control path serviceable without confusing shared and dedicated isolation boundaries.
One delivery-pressure setting cannot satisfy tools with different inlet limits or normal flow demandsSpecify a regulator range and local indicator for each stick, then commission every branch against its own downstream operating envelope.
Servicing a valve on one outlet can force an unnecessary shutdown of all connected equipmentPlace positive upstream and downstream isolation on every branch so the affected stick can be secured independently.
Residual gas and ambient moisture can enter the common header when a tool connection is openedUse a branch-specific compatible purge or evacuation path between the two isolation boundaries before disturbing the outlet joint.
An open panel may be selected for a gas that actually requires exhausted containmentLimit the VMP to gases and locations approved for open distribution; use an exhausted manifold box when the hazard review requires containment and airflow monitoring.
Mixed stick layouts make valve sequence, flow direction and outlet ownership difficult to verifyUse uniform component order, consistent flow arrows, permanent port tags and repeatable spacing across all four sticks.
A facility alarm may close the source but leave uncertain trapped volumes across individual branchesCoordinate the normally closed common inlet and selected stick shutdown valves with pressure feedback and a documented purge state for each outlet.

Technische Parameter
The catalogue basis follows the Stainless Design Concepts FlexGas four-stick VMP class: an open modular UHP panel approximately 470 mm wide, 533 mm high without the controller and 686 mm high with the selected control module. The wetted path uses electropolished 316L stainless tubing, diaphragm valves, regulators and service fittings, with one common inlet and four separately controlled outlets. Panel depth is configuration-dependent and a representative published envelope is approximately 222 mm. Gas compatibility, pressure range, flow, valve actuation, purge or evacuation method, filtration, instrumentation and automatic shutdown logic are selected for the actual service.
