Kerotest / Marsh "N" Series Needle Valves |
|
| |
Hard Seat Alloy Steel |
|
Soft Seat Standard Port |
|
|
Designed for air, water, oil, and other fluids with low level corrosiveness, this is a sturdy and economic choice for regulating pressure up to 10,000 PSI. The stem is 416 hardened stainless steel with body and bonnet made from AISI 1213 or 1215 alloy steel. |
 |
This valve series will provide a high level of performance where a bubble-tight seal and shut-off of liquids and gases are required. Durable and field proven, these valves come with a replaceable Delrin® sleeve insert for added life. |
| |
Miniature |
|
Soft Seat Full Port |
|
|
With a body length less than 2" and a maximum height of 2 1/2" (fully open), these valves are ideal for limited space applications. Precision machined stem delivers perfect centricity and roll-formed stem threads provide longer life. |
 |
Designed with a bubble-tight shutoff, a large bore size (0.257") that enables cleanout with rod and a straight-through design that reduces pressure drop, decreases turbulence, and improves flow. With a pressure rating to 6000 PSI, this series is ideal for gas transmission, metering, and flow recorders. |
| |
Hard Seat 316 Stainless Steel |
|
Hard Seat 316 Stainless Steel NACE |
|
|
Designed with a minimum burst pressure of 20,000 PSI and temperature limits from -100° to 800° F., this valve series is made with Teflon® packing and optional Grafiflex for high temperature service. |
 |
This valve series will meet or exceed safety standards in petroleum and gas production, pipeline service, offshore drilling, and any sour fluid environment that can cause sulfide stress cracking. Meets NACE standard MR-01-75 for resistance to sulfide stress cracking. |
| |
Block / Bleed Terminal 316 Stainless Steel and Alloy Steel |
|
|
|
Designed to reduce cost and increase reliability. These valves provide extra pressure outlets, permit line samplings, isolate gauges, provide a bypass, and eliminate extra connections and parts on a gauge leg. |
