Q: Can this valve be used for seawater applications?
A: Yes, we offer stainless steel or duplex material options, along with anti-corrosion coatings, making it suitable for seawater ballast and bilge systems. -
Q: What hydraulic pressure is required for the actuator?
A: The standard actuator operates at 6-10 bar hydraulic pressure. Custom actuator pressures can be arranged upon request for your existing system. -
Q: Is the valve supplied with a manual override?
A: Yes, every hydraulic shut-off valve includes a manual handwheel or lever for emergency operation or when hydraulic power is unavailable. -
Q: What are the available end connections?
A: Flanged ends in GB/T, ANSI, or DIN standards are standard. Threaded and welded ends are available as custom options. -
Q: Does the valve comply with SOLAS or other marine regulations?
