Page 5: Introduction
Installation, Operation, and Maintenance Manual 1. Introduction The 34 Series electronic actuated pilots offer accurate and reliable control of the valve. 34 Series pilots are a 4-20 mA standalone actuated controller calibrated via PC through a maintenance port and able to remotely control any Cla-Val valve. The pilot setting can be adjusted with a standard 4-20 mA signal, and 4-20 mA position feedback is available to cross check if requested position is reached. - Page 6 They allow for remote valve set point control, are ideal for use with SCADA systems and can be adjusted to accommodate changing requirements. The 34 Series Pilot Control can be easily retrofitted to an existing valve in the field without removal from the pipeline.

4. Applications 4.1 CRD-34 & CRA-34 The CRD-34 and CRA-34 are installed on the Cla-Val 390 Series valves that maintain downstream pressure and require this pressure to be changed from a local/remote location. It can be an effective solution for lowering costs associated with "confined space" requirements by eliminating the need for entry in valve structure for set-point adjustment. -

Installation, Operation, and Maintenance Manual 4.2 CRL-34 The CRL-34 is installed on Cla-Val 350 Series valves to maintain constant upstream pressure within close limits and allows this pressure to be changed from a remote location. This pilot can be an effective solution for lowering costs associated with "confined space" requirements by eliminating the need for entry in valve structure for set-point adjustment. -
Page 12: Cdhs-34
The CDHS-34 Is installed on Cla-Val 340 Series valves to maintain flow rate and allow the flow rate to be changed from a remote location. Additional pilot controls, hydraulic and/or electronic, are also available to perform multiple functions to fit exact system requirements. -

Page 18: Static Calibration
Cla-Val 34-Series Installation, Operation, and Maintenance Manual Figure 9: e-Drive Screen Layout. 6.2 Static Calibration Static Calibration is a fast and convenient method of calibrating the actuator by calculating the 4 and 20 mA values rather than raise or lower the actual system pressure. Dynamic Calibration requires that the system pressure is raised and lowered to the system values desired. -
Page 19: Number Of Psi Per Turn Calculation Example
• The pressure desired at 20 mA is 30 Psi. • Spring range for the 34 series is 15-30 Psi. • The number of turns to Low set point is equal: Pressure difference = 22 psi – 15 psi = 7 Psi. - Page 20 Installation, Operation, and Maintenance Manual After calculating low point and high point based on the spring range of the 34 series actuator and having a static calibration, values should be entered in the software accordingly low point and high point and write set range as shown in figure below.
