الأسئلة:
What materials are used in the construction of this control valve?
The valve body and bonnet are made from materials like WCB, WCC, WC6, CF8, CF8M, or CF3M. The valve spool and seat are typically 304, 316, or 316L stainless steel, with options for overlaying Stellite alloy for enhanced durability.
What is the operating temperature range of this valve?
The standard type operates from -20°C to 230°C. Special types include heat dissipation (up to 595°C), cryogenic (down to -196°C), and bellows seal (up to 350°C or down to -196°C), depending on the model and sealing materials.
How does the pneumatic diaphragm actuator work?
The actuator uses a multi-spring system to convert air pressure into linear displacement, controlling the valve opening. When paired with a positioner, it translates current signals into precise valve adjustments for optimal fluid parameter control.
What are the available flange standards for this valve?
The valve can be customized to meet various flange standards, including JB/T79, GB/T9113, HG/T20592, ANSI, JIS, and DIN, ensuring compatibility with different piping systems.
