Customer Benefits

Reduced Noise Levels 

The optional Lo-dB trim designs offer single-stage and doublestage noise attenuation benefits. Noise reduction levels of up to 25 dBA are possible, depending on the specific operating conditions.

Extended Life Cycle

Optional Anti-Cavitation trim is also available in single-stage and double-stage configurations. Proper control of dynamic cavitation conditions is extremely important for maintaining the continuous high performance and reliability of control valves.

Lower Costs

Dependable tight shut-off of a control valve helps to reduce the loss of process fluids, and can help eliminate the need for separate isolation valves. The optional soft-seat design provides bubble-tight shutoff capabilities in accordance with ANSI/FCI and IEC requirements.

Clean Air Compliance
The optional LE* (Low Emission) Packing system helps to reduce atmospheric emissions from the stem seal area. This unique feature helps to promote compliance with environmental safety and emissions control requirements.

Hazardous Emissions Control
The optional Bellows Seal configuration is well-suited for applications involving highly toxic and dangerous fluids. Positive sealing and extended life-cycle operation combine to promote reliable and safe operation.

Low Temperature Operation
The 21000 Series valve is also available in a cryogenic configuration for effective process control performance at extremely low temperature conditions. This is accomplished by using a combination of extended bonnets and construction materials.

Improved Process Yields
The 21000 Series can be equipped with various Masoneilan advanced digital positioners and controllers for enhanced performance and control. This results in improved process yields and real-time diagnostics capabilities to support predictive plant maintenance programs. BHGE offers the Masoneilan SVI* II AP (Advanced Performance) with HART® communications and the Masoneilan SVI FF for FOUNDATION® Fieldbus applications. Both instruments are available in single- or double-acting configurations and offer advanced control technology to provide enhanced precision for pneumatically actuated control valves. We also offer the Masoneilan Valvue* Software Suite for PC-based communications with these advanced devices.
