CVEZ Series Trim• Typically used for small valve applications• May be utilized when higher flow rangeability is required• Preferred for severe service or “dirty” applications• Available from 1” to 4” nominal bore• 8 Cage Trims Available (Equal Percentage, Linear, Equal Percentage 1-3, Linear 1-3)

The CVEZ Series is a non-balanced single seated construction control valve. Since dynamic flow forcesagainst the valve plug are somewhat higher, the CVEZ Series is typically reserved for small valve applications. Additionally, the CVEZ Series may be utilized when higher flow rangeablitiy (turndown) isrequired.

CVET Series Trim• Typically used with large control valve applications• Features interchangeable Kwik-ChangeTM Cages• 8 Cage Trims Available (Equal Percentage, Linear, Equal Percentage 1-3, Linear 1-3)• Available from 1” to 8” nominal bore

The CVET Series is a cage-guided design control valve typically used with large control valve applications. The balanced seat desgin of the Series provides excellent shutoff characteristics with reduced actuatorforce requirements. Additionally, the CVET Series features PTFE seating surface within the seat ring. TheCVET Series also features a weide array of interchangeable Kwik-ChangeTM Cages for variable flow characteristics or noise attenuation.

41005 Series Trim• Typically used for low noise applications• High Pressure Drop capabilities• 8 Cage Trims Available (Equal Percentage, Linear, Equal Percentage 1-3, Linear 1-3)• Available from 1” to 12” nominal bore

The 41005 is typically used for applications that require high noise attenuation. The multi-stage noise trim provides an unmatched level of noise performance. The smaller holes on the cages, although sacrifice some capacity, provide a high degree of noise attenuation. In addition to noise attenuation, the 41005 series valve provides excellent anti-cavitation performance.

Linear Piston Actuators(High Pressure Power Gas)

Becker Linear Piston Actuators (LP Series) are generally utilized whenavailable power gas pressures are higher than 50 psig. The high-pressure capabilities of the Linear Piston Actuator allows for smalleractuators sizes due to increased power gas pressures. Additionally, the high pressure capabilities of the Becker LP Series Actuator allowfor the use of Becker’s unique “bleed to pressure system” feature. Thisfeature completely eliminates bleed gas by maintaining control instru-mentation discharge within the pipeline system. Becker LP SeriesActuators are available in Double-Acting (DA) or Spring Return (SR)design for guaranteed failure mode of the control valve in the event ofloss of power gas. The Spring-Return LP is available in Spring-to-Closeor Spring-to-Open designs and is easily field-reversible.

Usage:• Pressure Control

For High Pressure Power Gas Applications where:• Minimum PSupply available < 50psig• “Bleed to Pressure System” feature is applicable

Benefits:• VRP-CH Series Pilots and LP Series Actuators enable unique “bleed

to pressure system” to eliminate atmospheric emissions• VRP-CH eliminates the need for a positioner• Constructed Specifically for use with natural gas• VRP-CH setpoint changes available from inches WC to 1300psig• LP Series Actuator accepts high pressure power gas, minimizing size

of actuator

Bleed to Pressure System Feature Eliminates Atmospheric BleedEmissions:Becker instrumentation has the unique ability to direct bleed gas down-stream or into a nearby lower pressure system. This eliminates atmosh-peric emissions, keeps gas in the pipeline, saves money for the operat-ing company, and reduces impact on the environment.

Sample Application #1

Usage:• Pressure Control

For low pressure power gas application with limited power gassupply pressure where:

• Minimum PSupply available < 50psig• “Bleed to Pressure System” feature is not avialable

Benefits:• VRP-SB-CH offers ZERO steady-state bleed gas• VRP-SB-CH eliminates the need for a positioner• Constructed Specifically for use with natural gas• VRP-SB-CH setpoint changes available from inches WC to 1300psig• LD Series Actuator provides high power output with low pressure

power gas

ZERO Steady-State Bleed Feature Minimizes Atmospheric BleedEmissions:Becker VRP-SB-CH Pilot Control Systems and HPP-SB Positionersoperate with ZERO steady state bleed. This reduces atmospheric emis-sions so long as the process variable setpoint is met. The only time theinstrument will bleed gas is when the LS Series diaphragm has toexhaust gas to relieve diaphragm loading pressure.
