NoShok 500 Series Standard, Soft Seat Needle Valve
The NOSHOK 500 Series Standard Soft Seat Needle Valve is a high-capacity valve designed for applications that require a bubble-tight shut-off and high flow rates. It features a replaceable soft seat and a straight-through porting design, which allows for bidirectional flow and makes it easy to clean using a rod.
This series is frequently used in oil and gas, chemical processing, and industrial automation where clean, efficient fluid or gas control is necessary.
Key Features:
-
Bubble-Tight Shut-Off: The replaceable Acetal soft seat ensures a zero-leak seal, even in high-pressure gas applications.
-
High Flow Capacity: The straight-through design provides a high flow coefficient (CV up to 4.0 for larger sizes), minimizing pressure drop.
-
Reliable Safety: Includes a blow-out proof stem that acts as a secondary seal when the valve is fully open.
-
Durable Stem Design: All stems are made from 316 Stainless Steel with rolled threads for increased strength and smooth operation.
-
Leak Testing: Every unit is 100% helium leak tested to 1 x 10-4 ml/s to ensure field reliability.
