Frequently Asked Questions (FAQ):
-
What is the main advantage of a lug-type butterfly valve over a wafer-type?
The lug design has threaded holes (lugs) on the valve body, allowing it to be bolted directly between two pipe flanges without needing long bolts through both flanges. This can simplify installation and removal, especially for end-of-line services. -
Why is NBR a suitable seal material for water applications?
Nitrile Rubber exhibits good resistance to water, oils, and many chemicals, along with excellent mechanical properties like elasticity and abrasion resistance, making it a durable and reliable sealing choice for water systems. -
Can this valve be used with other fluids besides water?
While designed and optimized for water, its compatibility with other mild fluids depends on the specific fluid properties. Consultation is recommended for non-water applications. -
What are the available actuator options for automated control?
The valve can be equipped with pneumatic (air) or electric actuators. The specific model and torque requirements depend on valve size and operating pressure. -
Is the valve suitable for high-pressure water systems?
The standard pressure ratings are PN10 and PN16. For higher pressure requirements, different material grades or valve designs may need to be considered. -
What is the typical delivery lead time for these valves?
Lead times vary based on order quantity, specific configurations, and current production schedule. Standard sizes and materials often have shorter lead times. -
Does the valve come with any standard accessories?
Typically supplied as a manual valve. Actuators, position indicators, or other accessories are optional and available upon request. -
How does the GB/T3036 standard benefit international buyers?
It provides a clear, standardized set of dimensions and performance criteria, ensuring the valve will fit and perform as expected in systems designed with or compatible with this standard.
