3 inch Ball Valve

Description

What is a 3 inch Ball Valve?

ZECO 3 inch ball valve is usually a floating ball valve, the material can also be divided into casting and forging two kinds.

2-Piece 3 inch Stainless steel ball valves with PTFE seals & seats. 3 inch stainless steel ball valves with PTFE (Teflon) seats & seals offer excellent corrosion resistance for most applications. Stainless steel & PTFE work well in applications including but not limited to water, oil, gas/air, light alkali and acids, biodiesel, fuels, and alcohols. These ball valves are fitted with tight seals to ensure no leakage and a long-lasting seal after many years of frequent usage.

Features of 3inch Ball Valve:

• Stem surface roughness is strictly restricted between Ra0.4 and Ra0.8, which ensures entry of graphite packing powder into tiny stem scratches to function as a lubricator, minimizing leakages around the stem. Max roughness of the stuffing box is RA3.2, which is a proper value to hold the packing ring in place and result in better sealing performance;
• The packing is a combination of parallel and vertical layers which is made of die-formed graphite ring processed by flexible graphite, characterizing heat resistance, less stress relaxation, and low creep. The special structure means low friction on the rotary stem, providing stabilized seal capability for the valve for a long time under frequent functioning;
• The Lip seal is the spring-energized seal, including Elgiloy or Inconel spring and PTFE jacket. it’s effective in a wide breadth of applications, such as highly corrosive chemical media, high sour gas, low temperature, or cryogenic service;
• ZECO strictly controls the quality of bulk products, with 100% inspection.

How do I choose a 3 Inch Ball Valve?

In order to choose the right Ball Valve, identifying the pressure level is also imperative because it will help in selecting the specialized valve with the material involved. Ideally, Ball Valves are available in stainless steel, ceramic, and even bronze for accentuating different types of liquid flow.
