Model C1

Product catalog summary
Basic Information
The document provides details on the Model C1, a pressure-reducing valve with a bellows design. It features a globe body, top entry, single-seated, two-way configuration with a multi-spring pneumatic actuator. The valve supports both direct and reverse actions and offers a modular design with various trim options. It operates with a Kv range of 3.5 to 115 m3/h and a Cv range of 4.0 to 134 gpm. The valve is suitable for liquids, compressed air, neutral gases, and steam, with temperature tolerances from -10 to 200°C and pressure ratings up to 50 barg.
Valve Parts and Materials
The valve components are made from materials such as ductile iron, bronze, carbon steel, and stainless steel, with specific parts like the seat, guide, and stem made from AISI 316L stainless steel. The seal is composed of PTFE and graphite, ensuring durability and reliability under various conditions.
Actuator Parts
The actuator components include a body, pillar, and support made from carbon steel, with springs made from SAE 9255 steel. The diaphragm is reinforced with EPDM fabric, and the actuator case is painted in epoxy for added protection.
Standard Configurations
The valve is available in sizes ranging from DN15 to DN100, with corresponding Kv and Cv values. The document provides detailed dimensions and weights for each size, ensuring compatibility with various industrial applications.
Actuator Dimensions and Weight
The document lists actuator models AP230, AP295, AP350, and AP430, detailing their dimensions, surface area, and weight. These actuators are designed to handle different pressure ranges and provide precise control over valve operations.
Bonnet and Stem Sealing
The bonnet is available in standard, extended, and finned configurations, with working temperatures ranging from -5 to +200°C. Stem sealing options include PTFE V-rings and graphite rings, suitable for pressures up to 50 bar and temperatures up to 350°C.
Flow Rate Coefficients and Pressure Drops
The document provides flow rate coefficients (Kv) for different valve sizes and outlines the maximum admissible pressure drops for various actuator signals, ensuring optimal performance under specified conditions.
Control Valve Accessories
The document mentions various accessories for the control valve, including positioners with features like auto/manual switches, zero and span adjustments, and HART communication capabilities.
Technical Specifications
The positioners are available in pneumatic, electro-pneumatic, and SMART configurations, with features such as linear motion, IP66 enclosure, and explosion-proof types. They support input signals of 4-20 mA DC and offer various output characteristics and communication options.
Disclaimer
The document concludes with a disclaimer stating that the information is subject to change without notice and advises users to verify technical data before use.
