304 Sus Keg Coupler Without Vent Vale A Type

The 304 stainless steel keg coupler without vent valve in A-type configuration from Yuhuan Meilanke Valve Co., Ltd is a beverage dispensing component machined from 304 austenitic stainless steel, a grade containing 18% chromium and 8% nickel that confers corrosion resistance against beer acids and cleaning chemicals. The omission of a vent valve simplifies the gas path, making this variant suited to single-pressure dispensing systems where carbonation levels are managed at the regulator rather than the coupler itself. A-type denotes the European Sankey profile, identifiable by its slotted probe and triangular gas-inlet geometry, which mates with corresponding A-type keg valves produced to DIN or brewery-specific standards.

304 stainless steel in this context offers particular advantages for hygiene-critical service: the alloy resists pitting from chlorinated cleaners and maintains passivation after repeated CIP (clean-in-place) cycles. The coupler body is typically investment-cast or machined from bar stock, with internal passages bored to precise tolerances to prevent turbulent flow and foaming. Surface finish is usually 180-240 grit or better internally, reducing nucleation sites for bacteria and biofilm. Sealing relies on replaceable EPDM or nitrile O-rings, with the probe engaging a stainless steel or brass keg valve body through a quarter-turn bayonet action. Typical working pressure is 2-3 bar, though the buyer should confirm burst-pressure ratings and thread specifications (BSPP, NPT, or push-fit) against their gas-distribution hardware.

This coupler serves commercial draft-beer installations, including pubs, restaurants, microbreweries, and mobile catering fleets. Buyers importing from Yuhuan Meilanke should verify whether the unit ships with a threaded gas tailpiece or requires separate procurement, and whether probe depth matches their keg valve standard (A-type probes vary slightly between German, Czech, and UK brewery specifications). The Yuhuan manufacturing cluster in Zhejiang Province specialises in brass and stainless steel valve components, though this particular listing's response rate of 0.00% suggests direct communication prior to order commitment is advisable.

Yuhuan Meilanke Valve Co., Ltd operates from Longwang Village, Chumen Town, Yuhuan City, Zhejiang Province, China, placing it within one of China's principal concentrations of low-pressure valve and plumbing fitting manufacture. The company's harbour trust tier indicates a baseline verification status on the platform, though the 0.00% response rate and zero recorded average response hours mean prospective buyers should treat initial contact as untested and allow additional lead time for quotation and sample dispatch. No workforce scale, annual revenue, or client list is provided in the source data, and none should be inferred.

The supplier's product focus, as evidenced by this listing, centres on stainless steel beverage-dispensing hardware for export markets. Buyers should note that the source description contains several unsubstantiated claims (flexible MOQ, competitive pricing, quality-assurance certifications) that are not backed by specific figures or certificate numbers in the data provided. Any certification claims (for example, food-contact material compliance to EU 1935/2004 or FDA 21 CFR) must be requested directly from Yuhuan Meilanke with accompanying documentation before order confirmation.
