People Also Ask (FAQ)
What is the technical difference between a lug type and a wafer type butterfly valve?
A lug type butterfly valve has threaded lugs on the outside of the valve body, allowing it to be bolted directly to the flanges. This means one side of the pipeline can be removed without affecting the other. A wafer type valve is sandwiched between two flanges and does not have lugs, meaning it cannot be used for dead-end service.
Can an SS304 lug type butterfly valve be used for dead-end piping service?
Yes, because the lugs are threaded and bolted directly to the flanges, an SS304 lug type butterfly valve can safely handle dead-end service. You can remove the downstream piping and the valve will remain securely bolted to the upstream flange.
What is the maximum working pressure and temperature rating for a PN16 SS304 valve?
A PN16 rating indicates a maximum working pressure of 16 bar (approx. 232 psi). The standard temperature range for an SS304 valve with an EPDM seat is -20°C to 120°C. If higher temperatures are required, a PTFE or Viton seat can be used.
Which Indian Standard (IS) or international standards (API/DIN) apply to PN16 lug butterfly valves?
These valves are typically manufactured and tested in accordance with international standards such as EN 593 (Europe), API 609 (USA), and ISO 10631. For Indian projects, they also comply with relevant IS standards for piping and flanges.
How do I calculate the breakaway torque to select an actuator for a PN16 SS304 valve?
Breakaway torque depends on the valve size, operating pressure differential, seat material friction, and fluid type. You can calculate it by multiplying the dynamic torque by a safety factor (usually 1.3 to 1.5). Request our technical datasheets for exact torque curves.
Is SS304 suitable for my chemical processing plant, or should I upgrade to SS316/SS316L?
SS304 is excellent for general water, mild chemicals, HVAC, and food-grade applications. However, if your chemical processing plant handles high concentrations of chlorides, halogens, or marine environments, you should upgrade to SS316 or SS316L due to the addition of molybdenum.
What flange drilling standards (ANSI B16.5 / DIN PN16 / IS 1536) are compatible with this valve?
Our SS304 lug valves can be machined to match various international flange drilling standards, including ANSI B16.5 Class 150, DIN PN10/PN16, EN 1092-1, BS 10 Table D/E/F, and IS 1536/IS 6392.
What is the difference between EPDM, PTFE, and Viton seats for SS304 lug butterfly valves?
EPDM is ideal for water, steam, and mild chemicals up to 120°C. PTFE (Teflon) offers excellent chemical resistance and handles aggressive acids up to 200°C. Viton (FKM) provides superior resistance to petroleum oils, fuels, and aromatic hydrocarbons up to 150°C.
How do you properly install and align a lug type butterfly valve between flanges?
Ensure the pipeline flanges are clean and aligned. Place the valve between the flanges, insert the bolts through the lugs, and hand-tighten them in a star pattern. Slightly open the valve disc before final tightening to prevent the disc from binding against the seat.
What hydro-testing and quality inspection certificates are provided with bulk SS304 valve orders?
Every bulk order is accompanied by an EN 10204 3.1 Material Test Certificate (MTC). We also provide hydrostatic pressure test certificates, dimensional inspection reports, and PMI (Positive Material Identification) reports upon request.
