4 Steps to Test Your Aerosol Valve Performance

A reliable aerosol valve can make or break a product. From spray feel to storage safety, mọi chi tiết đều có giá trị. If you’re working with an aerosol can valve, thiết bị truyền động van, or full aerosol dispensing system, these checks keep performance tight and consistent. Hãy chia nhỏ nó một cách thực tế.

Bước chân 1: Verify Assembly Tolerance and Crimping Specifications

When testing an aerosol valve, start with how parts fit together. Poor assembly tolerance or off-spec crimping specifications often cause leaks before the product even leaves the line.

Inspect core valve components
Measure actuator fit
Confirm can interface alignment

Check mounting cup dimensions
Evaluate gasket material compression
Đo đường kính và độ sâu uốn

Look closely at:

◎ Uniform curl under the cup
◎ No distortion at the sealing edge

If the mounting cup and gasket don’t seal cleanly, pressure loss happens fast. A well-built aerosol dispensing valve should sit tight without crushing internal parts. Tại FANXUN, tight tolerance control keeps deformation low and repeatability high.

Bước chân 2: Measure Spray Rate and Flow Characteristics

Spray performance tells you how the aerosol valve behaves in real life. Users notice it instantly.

Kiểm tra chính bao gồm:

Spray rate stability
Discharge rate under different propellant type
Required actuation force

Flow depends on:

Thiết kế vòi phun
Orifice size
Độ nhớt của sản phẩm

Các đợt ngắn. Long holds. Sử dụng lộn ngược. Test them all.

If flow feels uneven, adjust nozzle geometry or match the valve better to formulation thickness.

Bước chân 3: Assess Leakage Rate and Pressure Rating

Pressure testing protects both brand and user. A single weak gasket seal can ruin storage stability.

Pressure Testing Reference Table

Mục kiểm tra	Giá trị mục tiêu	Kiểm tra áp suất (thanh)	Khoảng thời gian (giờ)
Tỷ lệ rò rỉ	≤0.3% wt	6	24
