3-Way Pneumatic Diaphragm Control Valve | SS304 Globe Valve | Flanged Connection

Product Overview

Лийшаш SS304 3-Way Pneumatic Diaphragm Control Valve is a high-performance, multi-functional control valve designed for precise regulation of steam, южышт, ӱй, газ, water, and other industrial fluids. Featuring a rugged stainless steel (SS304/SS316) globe valve body and a pneumatic diaphragm actuator, this valve provides accurate flow control with multiple flow characteristics — equal percentage, linear, and quick opening. The flanged ends conform to PN25, PN40, ANSI Class 150-1500, and JIS standards, ensuring compatibility with international piping systems. Available in sizes from 3/4″ to 12″ (DN20-DN300) with single-seat, double-seat, or plug-type sealing options, this valve is suitable for a wide range of demanding applications. With OEM/ODM customization support, a 1-year warranty, and multi-spring or diaphragm actuator options, this valve is the ideal choice for chemical processing, power generation, ОВК, and steam systems requiring reliable, precise flow control.

FAQ

Q1: What is the difference between a pneumatic diaphragm control valve and an electric control valve?

ИК: Pneumatic control valves are driven by compressed air; they offer fast response, high thrust, and explosion-proof capabilities, making them suitable for hazardous areas and frequent operation. Electric control valves are driven by electricity; they offer higher precision and require no air supply, making them suitable for locations lacking compressed air systems. The choice depends on on-site air supply conditions and control precision requirements.

Q2: What is the difference between equal percentage, linear, and quick-opening flow characteristics?

ИК: Equal percentage: Flow rate changes logarithmically with valve opening; suitable for temperature and pressure control with high regulation precision. Linear: Flow rate changes in direct proportion to valve opening; suitable for flow and liquid level control. Quick-opening: High flow is achieved at small valve openings; suitable for on/off control.

Q3: What is the difference between single-seat and double-seat sealing?

ИК: Single-seat sealing: Low leakage rate (ANSI Class IV-VI), suitable for tight shut-off applications, though it requires higher thrust for high differential pressures. Double-seat sealing: Higher leakage rate (ANSI Class II-III) but requires lower thrust and offers high flow capacity; suitable for large-bore and high differential pressure applications.

Q4: Can this valve be used for steam?

ИК: Ооба. This valve is suitable for saturated and superheated steam, with a maximum temperature of +230°C (PTFE seal). For higher-temperature steam applications, flexible graphite or metal seal configurations are available. Please specify the steam operating conditions when placing your order.

Q5: Can the valve material be upgraded to SS316L or alloy steel?

ИК: Ооба. We offer material upgrade options such as SS316L, duplex stainless steel, and alloy steel, suitable for highly corrosive media, high-temperature/high-pressure environments, or special operating conditions. Please specify your requirements when placing your order.
