Is Your Current Valve Supplier Costing You Time, Space & Money?

In competitive industrial markets, every inch of pipeline space and every dollar of maintenance matters. Yet many purchasing managers face these recurring frustrations:

Excessive valve length – Standard lug or wafer designs require more pipe space and additional gaskets, increasing installation complexity.
High landed costs – Imported valves from traditional suppliers often carry premium prices plus shipping delays, eating into your margins.
Unreliable sealing – Low-quality discs and liners lead to leakage, unplanned downtime, and expensive repairs.
Long lead times – Custom sizes or materials (ductile iron, stainless steel) take weeks or months, stalling your projects.
Inconsistent quality – “Cheap” alternatives from some overseas sources fail pressure tests, risking safety and compliance.

These pain points are especially acute for double flanged short pattern butterfly valves used in critical isolation applications – where corrosion resistance and bubble-tight shutoff are non-negotiable.

“We once had a shipment from a competitor where 40% of valves failed hydrostatic testing. The project delay cost us over $18,000.” – Facility Manager, Texas Water Utility

Frequently Asked Questions About Double Flanged Short Pattern Butterfly Valves

What does “short pattern” mean in a double flanged butterfly valve?

Short pattern refers to a reduced face-to-face dimension compared to full-length (long pattern) valves. For double flanged butterfly valves, the short pattern follows EN 558 Series 14, making them lighter and more compact, ideal for tight piping spaces and lower structural loads.

Can I use this valve for potable water applications?

Yes, when fitted with an EPDM or WRAS-approved seat lining, the double flanged short pattern butterfly valve is suitable for potable water. We also offer FDA-compliant lining for food contact.

What is the typical lead time for standard sizes?

For sizes DN50–DN300 (2″–12″), we can ship within 15–25 working days from order confirmation. Larger sizes or special materials may require 30–40 days. We also offer express production for urgent orders at a small premium.

Do you provide OEM/ODM services for custom flange drilling or gearbox?

Absolutely. We regularly produce valves with customer-specific flange dimensions (ANSI 125/150, PN10/16, JIS 10K), stub shaft extensions, handwheel gearboxes, and electric/pneumatic actuator mounting brackets. Just send your drawing or specification.

How do you ensure quality and avoid leakage?

Every valve undergoes 100% shell and seat pressure test according to API 598. We also perform random torque tests and dimensional checks. A quality certificate accompanies every shipment.

What is the minimum order quantity (MOQ)?

For standard sizes, MOQ is 10 pieces per size. For custom designs, MOQ may start at 50 pieces depending on complexity. We can also accept sample orders for qualification.

How do you handle shipping costs to the USA?

We work with reliable freight forwarders and can quote CIF terms to major US ports (Houston, Los Angeles, New York). For full container loads (FCL), shipping cost per unit is significantly reduced; we help you consolidate.

Do you offer after-sales technical support?

Yes. Our engineers are available via email, WhatsApp, or video call to assist with installation, troubleshooting, and valve selection. We also provide spare liners and seals for maintenance.
