エアゾール缶商品で作動力に影響を及ぼす要因､決定する要因には､スプリングの力（荷重）とステムラバーの硬さ､それにエアゾール缶商品の内部圧力があります。ステムラバーの硬さと内部圧力の変更は難しいので､作動力の調整は主にスプリングの荷重を変更して対応することになります。弊社では一般バルブ用に荷重の異なるスプリングを用意しております。
バルブの種類や製品の種類によってはスプリングを変更できないものもございます。
又､作動力を軽くする目的でヒンジのついたテコ式ボタンもご用意しております。
ポンプ商品の作動力に影響を及ぼすものには､スプリング荷重の他に原液（内容液）の粘度とピストン弁の摺動抵抗､シリンダーの内径､吐出口などの流量抵抗（穴径）が関係します。
ご使用用途に適合した設定をご提案いたしますので､弊社営業にご相談ください。

Factors affecting and determining the spray load of aerosol cans include the strength of the spring (spring load), hardness of the stem rubber, and inner pressure of the aerosol can. As it is difficult to change the hardness of the stem rubber and the inner pressure, the spray load is changed by adjusting the spring load. We have various springs with different loads for our standard valves. However, the spring load cannot be changed in some products depending on the type of valves or products. We also have trigger type products with a hinge which has a smaller spray load. Factors affecting the spray load of pump products include the spring load, viscosity and sliding resistance of the content, the internal diameter of the cylinder, and the flow resistance of the jet nozzle (internal diameter). We may change the above factors and prepare a product your consumers prefer. Please consult our sales representatives. We will offer you the most appropriate specifications for your product.
The change of the function load automatically leads to a change of the spray load for pump products. Although it is basically possible, there are limitations due to the viscosity of the contents. As it depends on the purpose of use of our product, please consult our sales representatives. We will offer you the most appropriate specifications for your product.
