FAQ
-
What is the difference between rising stem and non-rising stem globe valves?
The rising stem moves upward when the valve opens, providing a visible open/close indicator. This design is preferred in applications where visual confirmation is important, such as ballast water systems. -
Can this valve be used for seawater in ballast water treatment?
Yes, the cast iron body is coated with a marine-grade epoxy paint to resist seawater corrosion. For even higher corrosion resistance, stainless steel trim options are available. -
Is the JIS F7305 10K equivalent to PN10?
Generally, 10K (JIS) and PN10 (ISO) have similar pressure-temperature ratings. Our valve is designed to meet both specifications, ensuring compatibility with systems using either standard. -
What sizes are available for immediate delivery?
We maintain stock for common sizes DN50, DN80, DN100, DN150, and DN200. Larger sizes and custom dimensions may require lead time. -
Can I operate the valve with an actuator instead of a handwheel?
Yes, we offer options for electric, pneumatic, or hydraulic actuators. Please specify your requirement when ordering. -
What is the maximum operating temperature?
The valve is suitable for temperatures up to 120°C (248°F) for water service. For higher temperatures, please consult our engineering team. -
Do you provide a warranty?
We offer a standard 12-month warranty against manufacturing defects. Extended warranty can be arranged upon request.
