FAQ

Q1: What is the difference between a resilient-seated gate valve and a metal-seated gate valve?

ΕΝΑ: Resilient-seated gate valves feature a wedge fully encapsulated in EPDM rubber, providing zero-leakage sealing (bubble-tight); they are suitable for water, sewage, και ήπιες χημικές ουσίες. Metal-seated gate valves (metal-to-metal contact) are designed for high temperatures (>150°C) and abrasive media but have a higher leakage rate (Class IV). For most water supply and HVAC applications, resilient-seated gate valves are the most cost-effective choice.

Ε2: What is the difference between Non-Rising Stem (NRS) and Outside Screw & Yoke (OS&Y) gate valves?

ΕΝΑ: NRS gate valves do not have a rising stem during operation, making them suitable for underground installations and valve pits where overhead clearance is limited. OS&Y gate valves feature a rising stem that provides a visual indication of the valve’s position, making them ideal for applications requiring visual confirmation of the open/closed status.

Ε3: What are the maximum working pressure and temperature ratings for this gate valve?

ΕΝΑ: The standard configuration is rated for PN16 (1.6 MPa / 16 μπαρ) with a temperature range of -10°C to +80°C. Optional configurations can extend the temperature range to -20°C to +120°C. Please contact our sales team for higher temperature or pressure requirements.

Q4: Can the valve body material be upgraded to stainless steel?

ΕΝΑ: Ναί. We offer stainless steel (SS304/SS316) body upgrades suitable for corrosive media, food-grade, or high-purity applications. Please specify your requirements when placing an order.
