FAQs of PTFE Lined Pressure safety Valve:
Q: What type of media is compatible with the PTFE Lined Pressure Safety Valve?
A: The valve is designed to handle acids as the media.
Q: What is the temperature range that the PTFE Lined Pressure Safety Valve can handle?
A: The valve can operate within a temperature range of -20 to 200 degrees Celsius.
Q: What is the application of the PTFE Lined Pressure Safety Valve?
A: The valve is suitable for chemical, oil, and agro-chemical applications.
Q: What is the disc material of the PTFE Lined Pressure Safety Valve?
A: The valve disc is made of Hastelloy C.
Q: What is the type of the PTFE Lined Pressure Safety Valve?
A: The valve is a spring-loaded type designed for high-pressure applications.
Superior Corrosion ResistanceOur PTFE lined safety valves are designed to handle highly corrosive media. The PTFE lining not only inhibits chemical attacks but also provides an anti-stick, smooth surface that prevents accumulations and makes maintenance straightforward. These valves are highly suitable for industries where aggressive chemicals are processed.
Reliable Leak Proof ProtectionThe valve's PTFE lined seat and disc offer Class VI leakage performance, ensuring a virtually tight seal and excellent emissions control. Its spring loaded mechanism with adjustable set pressure ensures reliable overpressure protection even at high stress, making it an ideal safeguard for sensitive equipment.
Flexible Installation and CompatibilityWith vertical installation recommended and flanged ends conforming to ANSI, DIN, or ISO standards, these safety valves can be seamlessly integrated into new or existing pipelines. The available port sizes from DN15 to DN100 (12" to 4") meet diverse operational requirements in a variety of industrial settings.
FAQ's of PTFE Lined Pressure safety Valve:
Q: How does a PTFE lined pressure safety valve provide chemical resistance?
A: The internal parts in contact with the process media are lined with minimum 2.5 mm PTFE. PTFE (Polytetrafluoroethylene) is highly resistant to most corrosive chemicals, which protects the valve body and internal mechanisms from aggressive media and increases the valve's service life.
Q: What is the recommended installation orientation for this valve?
A: It is recommended to install the PTFE lined pressure safety valve in a vertical orientation. This ensures optimal spring operation and maintains the designed set pressure performance.
Q: Where can this pressure safety valve be used?
A: This valve is specifically designed for use in industries such as chemical processing, pharmaceuticals, petrochemicals, and water treatment plants. Its PTFE lining and corrosion-resistant properties make it suitable for handling corrosive liquids and gases.
Q: What benefits does the Class VI leakage rating provide?
A: Class VI leakage means the valve delivers an extremely tight shutoff, minimizing process fluid loss and controlling fugitive emissions. This high level of tightness ensures operator safety and environmental compliance.
Q: How is the set pressure of the safety valve determined and adjusted?
A: The valve features a spring loaded control system. The set pressure, ranging from 0.5 bar to 10 bar, is determined and adjusted manually in accordance with system safety requirements and is factory-calibrated as per the customer's specifications.
Q: What maintenance is required for PTFE lined safety valves?
A: These valves are designed to be largely maintenance-free due to their anti-stick PTFE surface and robust construction. However, periodic inspection for external paint condition and spring tension is advisable for optimal performance.
Q: Can the valve be used with both liquids and gases?
A: Yes, the PTFE lined pressure safety valve is suitable for both corrosive liquids and gases, providing reliable overpressure protection in various media types within its specified pressure and temperature limits.
