Valve Product

2020/2120 SERIES 2-VALVE LIQUID LEVEL MANIFOLD VALVES NOSHOK 2-VALVE LIQUID LEVEL MANIFOLD VALVES are designed for use with differential pressure transmitters in liquid level applications. These valves are available in either single flange or double flange connection for direct installation. The soft seat design features a replaceable Delrin® seat with straight through porting for bi-directional flow and easy roddable cleaning.

2070/2170 SERIES BLOCK & BLEED 2-VALVE NEEDLE VALVES NOSHOK BLOCK & BLEED 2-VALVE NEEDLE VALVES combine isolating and venting in a single valve, eliminating the need for tubing and fittings. The block valve isolates the downstream process fluids, and the bleed valve exhausts upstream fluids enabling instruments to be removed without disturbing the permanent piping installation. The 1/4" NPT vent plug may be removed and replaced with exhaust piping to direct the fluids to a safe location. The metal-tometal hard seat design is pressure rated to 10,000 psi @ 200 °F and the soft seat design, with a replaceable Delrin® seat, is rated to 6,000 psi @ 200 °F. The all 316 stainless steel blow out proof stem provides greater service life and a secondary stem seal in the full open position. The standard stem seal is below the threads and protects against galling and corrosion.

3010/3110 SERIES 3-VALVE DIFFERENTIAL PRESSURE MANIFOLD VALVES NOSHOK 3-VALVE DIFFERENTIAL PRESSURE MANIFOLD VALVES are designed for use with differential pressure transmitters incorporating two isolation valves and an equalizing valve in differential pressure measurement. These valves are available in block, single flange or double flange connection for remote or direct installation. The soft seat design features a replaceable Delrin® seat with straight through porting for bi-directional flow and easy roddable cleaning.

400/500 SERIES STANDARD NEEDLE VALVES NOSHOK STANDARD NEEDLE VALVES are the work horses of the industry. The 400 Series’ metal-to-metal hard seat design is pressure rated to 10,000 psi @ 200 °F and helium leak tested to 1x10-4 ml/s for guaranteed performance and reliability. The 500 Series valves are fitted with a precision molded, replaceable Delrin® soft seat which is the key to the bubble tight seal. They have a maximum pressure rating of 6,000 psi @ 200 °F with straight through porting for bi-directional, high capacity flow and easy roddable cleaning. The all 316 stainless steel blow out proof stem provides greater service life and provides a secondary stem seal in the full open position. On the 400 Series, the stem and the one piece bonnet threads are rolled for greater strength and ease of operation. Both the 400 and 500 Series feature stem seal below the threads to protect against corrosion and galling.

SV SERIES STABILIZED CONNECTORS WITH INTEGRAL VALVE NOSHOK STABILIZED CONNECTORS WITH INTEGRAL VALVE are also designed to reinforce an installation by shifting radial-stress load away from the NPT connections, but also feature a block valve that can be installed on either side of stabilized body, allowing 1/2 turn installation. SV Series Stabilized Connectors with Integral Valve are available in zincnickel plated carbon steel and 316 stainless steel, and feature slotted bolt holes that allow for 2-1/8" and 2-1/4" bolt spacings.The integral valve has a 0.375" bore for unrestricted passage of process gas, and a standard non-rotating stem tip. This application will work on both flat surfaces (orifice fitting) and round surfaces (orifice flange) with flange adaptor. A single piece dielectric gasket (DK1) is available as an option to create a non-conductive shield between the process piping and the instrument. A two piece dielectric kit (DK2) is also available as an alternative when a separate sealing gasket or o-ring is required. Stainless steel bolts are also available.
