Description

AMAT 0190-87725 – Pneumatic Angle Valve

Product Overview

The AMAT 0190-87725 is an Applied Materials pneumatic angle valve used in semiconductor manufacturing equipment vacuum systems. Available industrial spare-parts references identify this part number specifically as a pneumatic angle valve, and listings place it within the vacuum, cryogenic, and flow-control category for Applied Materials equipment.

An angle valve of this type controls isolation of a vacuum or process-gas path, allowing equipment sections to be opened, closed, or separated during wafer-processing operations and maintenance. Its pneumatic actuation makes it suitable for automated tool operation, where valve state must be controlled by the equipment’s pneumatic and interlock systems. Publicly available sources do not provide a sufficiently reliable complete pressure, port-size, seal-material, or temperature specification, so those values should be confirmed against the applicable AMAT tool documentation before installation.

Technical Specifications — 0190-87725

Third-party listings consistently identify the part as an AMAT 0190-87725 Pneumatic Angle Valve, including listings describing working surplus units manufactured in the United States.

Key Features and Benefits — 0190-87725

• Pneumatically actuated valve for automated equipment control.
• Angle-valve configuration suited to compact semiconductor vacuum-system layouts.
• Designed for Applied Materials equipment rather than general-purpose industrial plumbing.
• Supports isolation of process or vacuum sections during operation and service.
• Relevant to MRO programs maintaining legacy semiconductor fabrication tools.
• Exact part-number identification helps avoid mismatched valve geometry or actuator configurations.

Personally, I would verify the complete valve label and tool configuration before ordering. Vacuum valves can look nearly identical while differing in port dimensions, sealing arrangement, actuator configuration, or allowable process conditions.

Installation and Maintenance — 0190-87725

Before installation, verify valve orientation, process-line connection dimensions, pneumatic supply requirements, actuator configuration, and the applicable Applied Materials equipment drawing. The process chamber or vacuum section should be safely isolated and depressurized according to the site procedure.

Inspect the valve body, bellows, actuator, fittings, and sealing surfaces for dents, contamination, corrosion, or mechanical damage. After installation, perform the approved valve actuation and leak-check procedure. For semiconductor equipment, cleanliness is particularly important because particulate or seal contamination can affect both valve performance and process stability.

Product Warranty — 0190-87725

Warranty coverage depends on supplier condition and procurement terms. Confirm whether the AMAT 0190-87725 is new, refurbished, or working surplus, and request inspection records, traceability information, leak-test results where applicable, and the stated warranty period.

For critical semiconductor-tool inventory, exact OEM identification should take precedence over visually similar pneumatic angle valves.
