Pneumatic High Pressure Control Valve

NSV Pneumatic High Pressure Control Valve

This pneumatic high-pressure control valve features a cast steel body such as LCB and is rated up to Class 2500. It provides precise modulating control of flow pressure or temperature in steam gas or liquid systems under low temperature or high pressure conditions. Designed per ASME B16.34. it ensures accurate and stable automated regulation through pneumatic actuation.

Key Features

LCB Low Temperature Carbon Steel Body ASTM A352 compliant for service down to minus 46°C with options in WCB WC9 CF8M for diverse process requirements

Up to 2500 LB Pressure Rating Suitable for critical high pressure control loops in demanding industries

Pneumatic Actuation Enables fast responsive and fail-safe modulation without electrical power

Robust Construction Suitable for continuous duty in refineries power plants and chemical facilities

This is NSV 10D Series, which can multi-hole low noise control valve adopts the sleeve guided structure and pressure balanced plug. lt is a high performance control valve with good dynamic stability that is suitable for severe service conditions.

As the differential pressure in the service conditions is relatively high and the flow velocity of media is high, the trims will be severely eroded and damaged and high noise will be produced. Therefore, we change the standard window-type sleeve into the multi-hole sleeve.

For liquids, the flow direction is generally high-in and low-out, and multi-hole throttling makes the media carry out collision inside the sleeve, so as to consume internal energy and reduce flow velocity.

For gas media,the flow direction is generally low-in and high-out, so that the gas media achieve volume expansion at the back of the seat after throttling by the multi-hole sleeve and the pressure of media is reduced to lower the flow velocity.

The parts of the101D Series are interchangeable with those of the 101T Series control valve except that the sleeve is changed into the multi-hole type.
