Caja de válvulas Manifold
A vented four-branch distribution enclosure that receives one high-purity gas supply, regulates and monitors each outlet stick, and isolates individual tool feeds without shutting down the remaining branches.
- Four independently isolated pressure-regulated outlet sticks
- Exhausted enclosure with common emergency inlet shutdown
- Electropolished 316L UHP flow path with purge-ready branches
Introducción del producto
The Valve Manifold Box is an enclosed secondary gas-distribution station installed between a centralized gas source and several process tools. The selected catalogue configuration uses one welded light-gray steel enclosure, one self-latching windowed access door, one top exhaust collar, one common inlet isolation assembly and four parallel distribution sticks. Each stick contains one compact pressure regulator, one pressure gauge, two diaphragm shutoff valves and one dedicated outlet. A local controller monitors permissives and can close the normally closed inlet emergency-shutoff valve while individual branch isolation lets an operator service one tool feed without disturbing the other three. The enclosure contains no gas cylinder and is distinct from an exposed single-source pressure panel, an open valve manifold panel and a bare pipe manifold.
Características clave
Independent branch shutoff allows one downstream line to be isolated while unaffected outlets remain available
A dedicated regulator and gauge on every stick provide branch-specific delivery-pressure adjustment and indication
Electropolished 316L tubing, diaphragm valves and low-dead-volume fittings protect purity through the distribution split
Purge-ready stick layouts support controlled displacement of trapped gas before a branch is opened for maintenance
A normally closed inlet emergency-shutoff valve provides one defined isolation point for local or remote alarm response
The clear safety window permits operating-state checks without opening the exhausted enclosure
Rail-mounted modular sticks simplify branch replacement, capacity changes and gas-specific component selection
Preocupaciones del producto del cliente
A manifold box must preserve gas purity and branch independence while coordinating enclosure exhaust, pressure control, purge routing and emergency isolation with the actual source and tool requirements.
Shutting the central gas source to service one tool branch can interrupt every process connected to that sourceProvide dedicated upstream and downstream isolation on each distribution stick so the affected branch can be secured without closing the other qualified outlets.
A single pressure setting may not meet the different delivery conditions required by four downstream toolsSelect an individual regulator range and pressure indicator for each stick, then commission each outlet at its normal tool demand.
Opening a contaminated branch can release residual gas or introduce moisture into the shared UHP headerIsolate the branch from both the common inlet and tool line, then use its compatible purge or evacuation route before breaking a connection.
A leak inside an unvented distribution enclosure can accumulate around multiple live jointsUse a continuously exhausted VMB configuration with monitored airflow and route the exhaust to the facility handling system selected for the gas hazard.
A local alarm may not isolate the common source quickly enough to protect all four outlet sticksTie the normally closed inlet emergency-shutoff valve to the local controller, external emergency signal and selected gas or exhaust alarms.
Branch additions can create mixed component standards, excessive dead volume or unclear valve sequencingUse repeatable rail-mounted stick modules with consistent flow direction, permanent port identification and gas-compatible UHP components.

Parámetros técnicos
The catalogue basis is a wall-mounted four-stick semi-automatic VMB in the Applied Energy Systems SEMI-GAS and Critical Systems compact four-stick class. A representative enclosure is approximately 559 mm wide, 381 mm deep and 1118 mm high before the external exhaust and utility connections. The wetted flow path uses electropolished 316L stainless tubing and diaphragm components, with one common inlet and four separately regulated outlets. Exact pressure range, valve actuation, purge or evacuation circuit, gas detector, fire sensor, exhaust duty, electrical supply and communications are selected for the named gas and facility.
