STREAMTEK

Manual Shut-Off Valve

MODEL: N/A Category

Streamtek™’s 304 Stainless Steel Manual Shut-Off Valves provide a rugged, corrosion-resistant solution for controlling airflow at the point of use. While standard brass valves may degrade in harsh environments, our Grade 304 Stainless Steel construction ensures long-term durability against moisture, chemical exposure, and high-pressure industrial demands. These high-flow ball valves are designed for “quarter-turn” operation, allowing operators to instantly cut or restore air supply to Air Knives, Cold Air Guns, Ionizers, or Nozzles with a simple flick of the wrist—eliminating the need to travel back to a main manifold or compressor.

Price range: 21.23$USD through 124.23$USD

Key Features & Benefits

  • Superior Corrosion Resistance: Grade 304 Stainless Steel is ideal for food processing, pharmaceutical, and wash-down environments where carbon steel or brass would oxidize or pit.

  • Full-Port Flow: Our valves are engineered with a full-bore internal diameter, ensuring your compressed air tools receive 100% of the required CFM without the restrictive pressure drops found in cheaper “standard port” valves.

  • Leak-Proof Performance: Featuring reinforced PTFE seats and a blowout-proof stem, these valves provide a bubble-tight seal even under high-vibration conditions.

  • Ergonomic Control: The high-torque handle is coated in a high-visibility vinyl grip, providing a non-slip surface for operators wearing gloves or working in oily conditions.

  • Blow-out Proof Stem: An essential safety feature that prevents the internal stem from being ejected under high-pressure spikes.

Installation Recommendations

For the most efficient setup, install the valve directly upstream of your Streamtek tool (such as an Air Knife or Vortex Tube). This allows for:

  1. Immediate Energy Savings: Easily shut off air during machine idle times or shift changes.

  2. Safer Maintenance: Isolate specific tools for cleaning or adjustment without depressurizing the entire plant line.
