NoShok 400 Series Standard, Hard Seat Needle Valve
The NOSHOK 400 Series Standard Hard Seat Needle Valve is a heavy-duty valve designed for high-pressure, high-temperature industrial environments. It features a robust one-piece bonnet with a metal-to-metal seal and a blow-out proof stem, making it a reliable choice for severe service applications in oil and gas or manufacturing.
Key Features:
-
High-Pressure Capacity: Rated for 10,000 psi for sizes up to 1/2 inch NPT and 8,000 psi for sizes up to 1-1/2 inch NPT.
-
Leak Integrity: 100% helium leak tested to 1 x 10-4 ml/s to ensure bubble-tight performance and safety.
-
Durable Construction: Bodies are made from zinc-nickel plated steel or electropolished 316 stainless steel, with all stems constructed from 316 stainless steel.
-
Smooth Operation: Rolled stem threads provide high strength and ease of movement, even under maximum pressure.
-
Safety Features: A slotted spring pin prevents accidental loosening of the bonnet, and the blow-out proof stem provides a secondary seal in the full open position.
