Frequently Asked Questions (FAQ):

Q: What is the primary advantage of having a manual override on a hydraulic valve?
A: The manual override is a critical safety and operational feature. It allows operators to open or close the valve manually in case of hydraulic power failure, system maintenance, or during commissioning/decommissioning procedures, ensuring system control is never lost.
Q: Why is 316L stainless steel specified for the trim instead of standard 316?
A: 316L has a lower maximum carbon content, which significantly reduces the risk of carbide precipitation during welding and in high-temperature service. This enhances its corrosion resistance, particularly against sensitization and intergranular attack in harsh environments like marine applications.
Q: Can this valve be used in "sour service" applications involving H2S?
A: Yes. The valve is designed and manufactured to be compliant with NACE MR0175/ISO 15156 standards for sour service, meaning the materials are selected and treated to resist sulfide stress cracking (SSC) in environments containing hydrogen sulfide.
Q: Is the PN16 pressure rating compatible with the 1500 PSI rating?
A: PN16 corresponds to a nominal pressure of 16 bar at room temperature. While 1500 PSI is approximately 103 bar, the valve's design pressure is 1500 PSI. The PN16 rating typically refers to the flange's pressure-temperature class. It is crucial to specify both the valve's design pressure and the required flange rating for your specific service conditions.
Q: What hydraulic pressure is required to operate this valve?
A: The standard hydraulic actuation package is designed for common industrial hydraulic pressures. The exact required operating pressure depends on the valve size and required torque. Specific pressure requirements can be customized upon request to match your existing hydraulic power unit.
Q: Are other end connections besides flanged available?
A: While flanged connections (RF, RTJ) are standard for DN80 and PN16/1500PSI applications, other end connections such as butt-weld ends or socket weld ends can be explored as a customization option based on your piping design.
Q: What is the typical lead time for this product?
A: As a manufacturer, we maintain production flexibility. Lead times vary based on order quantity and current production schedule. Generally, standard configurations have shorter lead times. Please inquire with our sales team for an accurate delivery estimate.
Q: Do you provide documentation like test reports and material certificates?
A: Yes. In line with our ISO9001 certification, we provide essential documentation, including material test certificates (MTC), pressure test reports, and a certificate of conformity. Detailed inspection and test plans (ITP) can be discussed for critical projects.
