Product Overview

Operating Mechanism (Drive Mode):
• Hydraulic Control: All valves operate based on hydraulic pressure, using diaphragm or piston actuators to control the opening and closing of the valve.
• Electric-Hydraulic Control: Valves like TG178, TG182, TG183 feature electric and hydraulic hybrid control, allowing for precise and remote operation.
• Remote-Controlled Operation: Certain models (e.g., TG173, TG176, TG181) are equipped with remote sensing capabilities for automated level control in tank systems.

Materials

• Body Material Options:
o Ductile Iron, Cast Iron, Carbon Steel, Stainless Steel
• Seat Materials:
o Soft Sealing (EPDM, NBR) for low-pressure systems
o Metal Sealing (Stainless Steel, Bronze) for high-pressure and high-temperature applications

Certifications:

• Compliance: API, ISO 9001, CE, PED, SIL certifications for safety-critical applications.
• Optional Explosion-Proof Certification: Available for electric control valves operating in hazardous environments.

Product Features

• Adjustable Pressure Regulation: Pressure reducing valves can be adjusted to meet specific downstream pressure needs, ensuring system stability and protection from overpressure.
• Remote and Automatic Control: The remote-controlled float valves offer automatic regulation of liquid levels in tanks, reducing manual intervention.
• Multi-Functional Control: The multi-function hydraulic control valves are designed to combine pressure regulation, flow control, and shut-off functions in a single unit.
• Safety Relief Mechanism: The safety relief valves are built to automatically release excess pressure, protecting system components from failure or damage.
• Angle-Type Connections: Angle-type float and sludge valves offer a compact, space-saving design suitable for installations in tight or limited spaces.
