o ON/OFF Type: For basic cut-off applications.
o Modulating Type: For flow control and precise regulation of fluid within the system.
o Explosion-Proof Options: Available for valves installed in hazardous or explosive environments.
• Control Features:
o Analog and digital signal control (4-20mA, 0-10V)
o Feedback and diagnostics
o Local control and remote monitoring options
Materials
• Body Material Options:
o Carbon Steel, Stainless Steel (304, 316, 316L)
o Cast Iron, Ductile Iron, Alloy Steel
• Seat Materials:
o Soft Seal (PTFE, EPDM, NBR) for low-pressure, non-corrosive applications
o Metal Seal (Stainless Steel, Inconel, Monel) for high-pressure, high-temperature applications
Certifications:
• Compliance: API, ISO 9001, CE, PED certifications, as well as SIL (Safety Integrity Level) for critical shut-off applications.
• Optional Explosion-Proof Certification: For valves installed in hazardous environments.
• Extended Stem Option: The extended stem gate valve (TG158) is designed for underground installations, providing easy access in remote or insulated environments.
• Self-Sealing Technology: Available in both globe and check valves, this feature ensures tight sealing even under high pressures, making these valves ideal for steam and thermal fluid systems.
• Y-Pattern Design: Y-type valves provide better flow characteristics and less pressure drop compared to traditional globe and check valves.
• Socket Weld Connections: Secure, high-integrity connections for use in critical systems where leak prevention is a top priority.
• Versatile Operation: Compatible with various electric actuators for precise flow control, cut-off, or regulation across a wide range of industrial applications.
