Frequently Asked Questions (FAQ)
-
What types of valves can this spanner be used on?
Our Valve Spanner is designed for most industrial valves with hexagonal or square stem flats, including gate, globe, plug, and butterfly valves. Please confirm your valve stem dimensions for a perfect fit. -
Is the spanner adjustable or fixed?
We offer both fixed-opening and adjustable models. Standard spanners are fixed. For variable stem sizes, adjustable versions with a movable jaw can be produced upon request. -
Can I get a custom length or handle shape?
Yes, we fully support customizations. Our engineering team can modify length, handle shape, and even add insulation or special coatings based on your application. -
What is the accuracy of the precision ground surface?
The jaw surface is ground to achieve a tolerance of ±0.05 mm for repeatable fit. Ra value is typically ≤1.6 μm, ensuring smooth engagement. -
Does the 1-year warranty cover accidental damage?
The warranty covers manufacturing defects in material and workmanship. It does not cover damage caused by misuse, over-torquing, or normal wear. Please refer to our warranty policy for details. -
What information is included in the Mill Test Report?
The MTR includes chemical composition, tensile strength, yield strength, elongation, and hardness test results for the specific heat-treated batch used in your spanner. -
