Product Description

1. Key Features
Superior Corrosion Resistance: Constructed from high-grade stainless steel (SS304/CF8, SS316/CF8M), ensuring excellent durability in harsh and corrosive environments.
Zero-Leakage Sealing: Equipped with high-performance PTFE or RPTFE seats, providing a bubble-tight shut-off for maximum safety.
Full-Bore Design: Features a full-port internal structure that allows for maximum flow capacity with minimal pressure drop.
High-Efficiency Actuation: Powered by a lightweight, hard-anodized aluminum pneumatic actuator, available in both Double-Acting and Spring-Return (Fail-Safe) configurations.
Standardized Mounting: Built with ISO 5211 mounting pads for easy integration of limit switches, solenoid valves, and positioners.

2. Core Functions
Automated Remote Control: Realizes rapid 90-degree rotary switching through pneumatic signals, enabling integration into automated DCS or PLC systems.
Rapid Response: Capable of high-speed opening and closing, making it ideal for systems requiring frequent operation and instant flow control.
Flow Regulation: When equipped with an electro-pneumatic positioner, the valve can perform precise proportional control of flow rates.
Fail-Safe Protection: The spring-return model automatically moves the valve to a "Normally Closed" or "Normally Open" position during an air supply or power failure.

3. Typical Applications
Chemical & Petrochemical: Handling aggressive chemicals, acids, and industrial solvents.
Food & Beverage: Ideal for sanitary applications due to its easy-to-clean, non-contaminating stainless steel surfaces.
Water Treatment: Automating water supply, wastewater management, and desalination systems.
Pharmaceutical: Precise control in sterile environments and biotech processing.
Energy & Utilities: Reliable management of compressed air, natural gas, steam, and oil distribution lines.

FAQ

1. What is the difference between PN and Class pressure ratings?
Answer: PN is the pressure rating used in European standards (e.g., DIN, GB), typically measured in bar (e.g., PN16 stands for 1.6 MPa). Class is the rating used in American standards (ANSI/ASME), such as Class 150. They cannot be converted simply because their reference temperatures and material strength curves differ.
2. How to choose between Stainless Steel 304 and 316?
Answer: SS304 is a general-purpose stainless steel suitable for water, oil, gas, and non-corrosive media. SS316 contains Molybdenum (Mo), which provides superior resistance to chloride corrosion and pitting, making it ideal for marine, chemical, or highly corrosive environments.
3. What are "Soft Seats" and "Metal Seats"?
Answer: Soft Seats use elastomers or plastics (like PTFE/Teflon). They provide excellent sealing (Zero Leakage) but have lower temperature limits (usually <200°C). Metal Seats involve metal-to-metal contact, offering high temperature and pressure resistance and durability against wear, though they may have a higher allowable leakage rate compared to soft seats.
4. Can NPT and G threads be used interchangeably?
Answer: No. NPT is an American Standard Taper Pipe Thread with a 60° thread angle. G is a parallel pipe thread (commonly British BSPP) with a 55° thread angle. Forcing a connection between them will result in seal failure or damage to the threads.
5. What is the difference between a Swing Check Valve and a Lift Check Valve?
Answer: In a Swing Check Valve, the disc swings on a hinge, offering lower flow resistance; it is commonly used for large-diameter pipelines. In a Lift Check Valve, the disc moves vertically along an axis, offering better sealing but higher flow resistance; it is typically used for small-diameter pipes.

6. Why do ball valves get damaged easily in a half-open position?
Answer: Ball valves are designed for full-on or full-off service. In a half-open position, the high-velocity flow strikes the exposed parts of the ball and seats, causing seat erosion or "wire drawing" on the ball, which shortens the valve's lifespan. For throttling, use globe valves or control valves.
7. What are Full Bore and Reduced Bore ball valves?
Answer: A Full Bore ball valve has a port diameter equal to the pipe's internal diameter, resulting in minimal flow resistance and allowing for "pigging" operations. A Reduced Bore valve has a smaller port than the pipe ID, which is more cost-effective and suitable for systems where pressure drop is not a critical concern.

8. What are the common causes of internal leakage in valves?
Answer: The primary causes include:
(1)Impurities (such as welding slag or sand) trapped on the sealing surface; 
(2)Erosion or wear of the sealing faces; 
(3)The valve not being fully closed;
(4)Incorrect selection (e.g., pressure or material exceeding limits).
9. How to choose between Double Acting and Single Acting (Spring Return) pneumatic actuators?
Answer: Double Acting actuators require air pressure for both opening and closing and are more economical. Single Acting (Spring Return) actuators use springs to automatically reset the valve to a "fail-safe" position (Open or Closed) upon loss of air pressure, making them ideal for critical safety applications.
10. What are the common certifications required for valve exports?
Answer: Common certifications include ISO 9001 (Quality Management), CE (European market access), WRAS (UK drinking water safety), and MTC (Material Test Certificate) for traceability.
