The 016742 shut-off valve is an essential control component used in Sullair screw air compressor systems to regulate, isolate, or stop airflow within the unit’s internal pipeline. Unlike safety valves that respond automatically to pressure spikes, this valve is manually or pneumatically actuated to provide controlled shutdown of specific flow paths. Its precise sealing structure and corrosion-resistant construction make it suitable for long-term use in environments where compressed air contains oil vapor, moisture, and temperature fluctuations.
This valve plays a crucial role during maintenance operations, system shutdowns, and emergency isolation procedures, helping protect key assemblies such as the airend, filters, regulator modules, and oil circuit components.
Structural Design & Core Components
The 016742 valve is engineered with a solid brass or alloy-steel body (depending on compressor version) that offers strong resistance to internal pressure and chemical exposure. The internal flow channel follows a smooth, streamlined geometry that minimizes turbulence and pressure loss, improving the compressor’s overall efficiency.
The valve stem is precision-ground to ensure consistent movement, reducing friction and preventing operational sticking. This stem works in conjunction with a reinforced sealing seat designed to maintain an airtight closure even after repeated actuation cycles. The seat material is selected for its elasticity retention and resistance to permanent deformation, guaranteeing consistent sealing performance over long periods.
The handle or actuator interface is firmly connected to the stem, allowing for stable and predictable opening and closing without backlash or drift. This contributes to a balanced control feel and precise flow management.
Reliable Sealing Performance
A standout feature of the 016742 shut-off valve is its tight, low-leakage sealing behavior. Sullair compressors rely on stable internal pressure to maintain efficiency, so any small leak can reduce system performance and drive up energy consumption. The sealing components in this valve are formulated to withstand the operating temperature range inside screw compressors, ensuring they do not harden or crack under continuous exposure to warm, oil-infused compressed air.
The valve maintains consistent closure pressure across its lifespan, preventing micro-leaks that often develop in lower-quality valves. The result is improved compressor stability, reduced load on the airend, and more predictable airflow behavior.
Heat, Pressure & Corrosion Resistance
Screw air compressors operate under long-duty cycles, often in facilities where ambient conditions fluctuate. The 016742 valve is built to handle:
- Continuous exposure to warm compressed air
- Intermittent oil mist and vapor
- Moisture from condensation
- Elevated pressure common in Sullair systems
The body surface features an anti-corrosion treatment that protects it from rust and chemical damage, even in humid workshops or dusty industrial areas. The internal components are selected to resist scale buildup, maintaining smooth operation and extending service life.
Manufacturing Precision & Quality Control
During production, each valve undergoes precise CNC machining to achieve tight tolerances on the seat, stem alignment, and internal channels. This prevents misalignment that could cause resistance during operation or premature seal wear.
Before packaging, the 016742 shut-off valve is tested under simulated compressor conditions. These tests verify:
- Smooth actuation at various pressures
- Leak-free sealing at rated closure torque
- Stability under thermal cycling
- Consistency across repeated opening/closing cycles
Only units that maintain stable sealing and mechanical integrity across all test conditions are approved for final delivery.
Application & Installation
This valve is compatible with a wide range of Sullair screw compressor models that rely on manual or controlled isolation points. It can be installed in oil-injected air circuits, separator tank lines, filter manifolds, or other parts of the pneumatic pathway where shut-off functionality is required.
Installation is straightforward: the mounting threads should be cleaned, sealing tape or gasket applied as required, and the valve tightened to the specified torque. After installation, a gradual pressure increase ensures the sealing seat adapts perfectly to the compressor’s internal pressure environment.
Advantages for Operators
The 016742 shut-off valve provides consistent, predictable flow control with a durable sealing interface designed for long-term reliability. Its corrosion-resistant structure and precise machining make it a dependable choice for workshops, manufacturing lines, and heavy-duty industrial operations using Sullair compressors.
