If you are looking for an Industrial butterfly valves manufacturer with quick engineering support and clear specifications, Yaxing Valve provides immediate RFQ responses and downloadable datasheets.

Product Scope & Configurations

As an Industrial butterfly valves manufacturer, we build standardized and custom configurations:

  ● Wafer Butterfly Valve – compact, lightweight; ideal for space-limited installations, easy alignment between flanges.

  ● Lug Butterfly Valve – threaded lugs allow end-of-line service or single-side removal; maintenance-friendly for pipelines and pump stations.

  ● Flanged Butterfly Valve – robust sealing and rigidity for large sizes and frequent cycling; recommended for municipal trunk lines and plant utilities.

  ● Concentric vs Double-Eccentric – concentric (resilient seat) for general service; double-eccentric lowers friction, reduces wear, and handles higher ΔP.

Technical Specifications

  ● Body: Ductile Iron (DI) / Cast Iron; optional stainless steel for special media

  ● Disc: DI with nickel plating / Stainless Steel

  ● Seat: EPDM / NBR resilient; metal seat on request

  ● Coating: Fusion-Bonded Epoxy (FBE) / Epoxy suitable for potable water versions

  ● Flange compatibility: EN 1092-2 / DIN / BS; wafer pattern suits PN10/PN16 bolt patterns

  ● Testing: shell and seat tests to EN 12266-1 (or equivalent) with records included

  ● Temperature: per elastomer and media; provide medium, temperature, and pressure in RFQ

Being an Industrial butterfly valves manufacturer, we keep critical components standardized to simplify spares, and we publish torque charts, Cv values, and dimensional tables to support system design.

Standards & Compliance

  ● EN 593 product requirements

  ● AWWA C504 build options available for North American specifications

  ● Project packs: MTC, hydrostatic/seat test report, coating inspection, and third-party witness (on request)

When you work with an Industrial butterfly valves manufacturer like Yaxing, you receive a traceable document set aligned to your project specification and submittal process.

Actuation & Accessories

  ● Manual: lever or gearbox (lockable)

  ● Pneumatic / Electric actuators with limit switches, position feedback, and optional positioners

  ● Options: corrosion-resistant packages, stem extensions, buried service kits, low-temperature elastomers

Our status as an Industrial butterfly valves manufacturer means actuators are sized against real torque envelopes, not catalog assumptions—reducing field adjustments and start-up risk.

Applications

  ● Water & Wastewater: trunk mains, treatment works, pump discharge, isolation and throttling

  ● HVAC & Building Services: chilled/cooling water loops, secondary pumping stations

  ● Fire Protection: sprinkler and ring main isolation (project-specific coatings/markings)

  ● Industrial Utilities: general non-abrasive fluids; consult us for chemical compatibility

For EPCs and distributors seeking an Industrial butterfly valves manufacturer, we offer framework pricing, safety stocks, and coordinated shipping for multi-site rollouts.

Selection Guide

  ● Wafer vs Lug: choose Lug for end-of-line service or single-side removal; Wafer when footprint and cost matter.

  ● Flanged: select for DN≥300, higher cycling, or where pipe rigidity improves sealing reliability.

  ● Seat/Coating: potable water—EPDM + FBE; hydrocarbon service—consider NBR; consult for special liners.

  ● Double-Eccentric: lower operating torque, less seat wear, better for higher ΔP and larger diameters.

FAQ

Q1. Are you an Industrial butterfly valves manufacturer or a trading company?
A. We are an Industrial butterfly valves manufacturer with in-house machining, coating, and assembly. We also provide OEM/ODM branding and custom documentation.

Q2. What sizes and pressure classes do you cover?
A. DN40–DN1200 in PN10/PN16 are standard. Larger sizes or different ratings can be discussed with our engineering team.

Q3. Can you supply actuated packages?
A. Yes—manual, pneumatic, and electric packages are engineered by an Industrial butterfly valves manufacturer to match torque envelopes, with feedback and controls as needed.

Q4. What documents are provided with shipments?
A. Datasheet, dimensions, MTC, pressure test report, coating inspection, and optional third-party witness—standard deliverables from an Industrial butterfly valves manufacturer.

Q5. How do I specify the right configuration?
A. Include DN/PN, wafer/lug/flanged, medium, temperature, pressure, actuator type, quantity, delivery window, and standards (EN 593 / AWWA C504). We’ll configure and quote accordingly.
