Frequently Asked Questions
-
What is the difference between this valve and a standard pressure reducing valve?
This valve is specifically designed for marine steam applications, with cast steel construction and DNV/BV type approval, making it suitable for use on ships and offshore platforms where classification society rules apply. -
Can the valve be used for non-marine applications?
Yes, it can also be used in industrial steam systems where high pressure and temperature resistance are required. However, for non-marine use, the DNV/BV certification is an extra guarantee of quality. -
What is the typical lead time for production?
Standard sizes (DN15-DN100) are typically produced within 15-30 working days, depending on quantity and customization. Contact us for specific lead times. -
Do you offer spare parts or repair kits?
Yes, we provide diaphragm kits, spring sets, and seat seals for maintenance. Please specify your valve model when ordering. -
How is the valve shipped?
We ship from Shanghai, Guangzhou, Hong Kong, or Beijing ports. Spare parts can be sent via air freight for urgent needs. -
Can the pressure setting be adjusted in the field?
Yes, the set pressure can be adjusted by turning the adjusting screw (for direct-acting types) or by adjusting the pilot valve (for pilot-operated types). Instructions are included in the manual. -
Is the valve suitable for superheated steam above 350°C?
Standard design is for up to 350°C. For higher temperatures, we can provide custom materials and seals upon request. -
What is the warranty period?
We offer a 12-month warranty from the date of shipment against manufacturing defects. Extended warranty options are available.
