Reliable Performance for Critical ApplicationsThis butterfly valve excels in water treatment, HVAC, fire fighting, and irrigation sectors. Its robust design, low leakage, and bubble-tight shutoff provide optimum safety and reliability, supported by hydrostatic pressure testing at 24 kg/cm2. The universal mounting and multiple connection options (wafer and flanged) make it a flexible choice for system designs requiring dependable flow control.
Engineered for Durability and SafetyFeaturing cast iron or ductile iron disc, stainless steel shaft, and fusion bonded epoxy coating, this valve resists corrosion and wear. Its seat materials-EPDM or NBR rubber-guarantee excellent sealing properties, while low operating torque enables effortless manual operation. Every piece meets strict ISI specifications and is designed for long-term service in varied environmental conditions.
FAQ's of PN 16 ISI Marked Cast Iron Butterfly Valve:
Q: How does the PN 16 ISI Marked Cast Iron Butterfly Valve provide bubble-tight shutoff?
A: The valve achieves bubble-tight shutoff through its specially designed EPDM or NBR rubber seat which forms a precise seal with the disc, effectively preventing leakage and ensuring reliable isolation of the flow media.
Q: What industries and applications is this butterfly valve suitable for?
A: This butterfly valve is ideal for water treatment, HVAC systems, fire fighting installations, and irrigation networks. Its versatile construction caters to the demands of managing water, gas, and oil media in these critical sectors.
Q: When should I choose lever versus gear operated butterfly valves?
A: Lever operated valves are recommended for smaller sizes where manual operation is straightforward, while gear operated options are preferable for larger diameters or higher torque requirements to enable easier actuation.
Q: Where can this valve be installed within a piping system?
A: The valve's universal mounting design and choice of wafer or double flanged ends allow installation in various pipe configurations, helping accommodate space or connection requirements in both new and existing setups.
Q: What is the standard for face-to-face dimensions and pressure testing?
A: The face-to-face dimensions adhere to IS:13095 or BS:5155 standards, and each valve undergoes hydrostatic pressure testing up to 24 kg/cm2 to verify its structural integrity and performance under pressure.
Q: How does fusion bonded epoxy coating benefit the valve?
A: Fusion bonded epoxy coating enhances the valve's resistance to corrosion and abrasion, ensuring longer service life even in aggressive water and industrial environments.
Q: What is the available size range and how do I select the right port size?
A: This butterfly valve is available from 50 mm to 600 mm port size. Selection depends on your pipeline dimensions and flow requirements. Consulting with your supplier or distributor in India can assist you in matching the correct size to your application.
