9.7mm LSR Silicone Flow Control Valve for Dishwashing Detergent Dispensing | Hopewell

2D Design of 9.7mm Silicone Flow Control Valve

What Is a Silicone Flow Control Valve?

A silicone flow control valve is a precision-molded elastomer component that automatically regulates liquid flow in dispensing packaging. Installed inside bottle caps or dispensing closures, the valve opens only when pressure is applied to the bottle and instantly reseals once the pressure is released.

This self-sealing silicone flow control valve prevents leakage, dripping, and backflow while ensuring smooth, controlled dispensing with every squeeze.

Manufactured from premium Liquid Silicone Rubber (LSR), Hopewell's 9.7mm silicone flow control valve offers excellent elasticity, and long-term durability. Designed specifically for dishwashing detergent dispensing, it provides reliable sealing, accurate flow control, and an improved user experience.

Besides dishwashing detergent packaging, silicone flow control valves are widely used in household cleaning products, personal care packaging, food and beverage dispensers, cosmetics, and medical liquid dispensing systems.

Key Features of Silicone Flow Control Valve?

Our food-grade silicone flow control valve is engineered for demanding liquid dispensing applications. Manufactured using advanced LSR injection molding technology, every silicone valve is designed to deliver consistent dispensing performance, superior sealing, and exceptional service life.

1. Precise Flow Control

The precision-engineered cross slit opens smoothly when the bottle is squeezed and closes immediately after pressure is released.

This intelligent self-regulating design provides:

Accurate liquid dispensing

Consistent flow rate

Reduced detergent waste

Cleaner dispensing experience

2. Leak-Proof & Anti-Drip Performance

Our one way silicone flow control valve creates a reliable seal that effectively prevents leakage during storage, transportation, and daily use.

The self-closing structure eliminates residual liquid around the bottle opening, keeping packaging clean while improving consumer satisfaction.

Every silicone valve is verified through 7-day continuous inverted leak testing (7 × 24 hours) to ensure dependable sealing performance.

3. Premium Food-Grade LSR Material

Manufactured from premium Liquid Silicone Rubber (LSR), our valves provide:

Excellent elasticity

High transparency

Long service life

Stable performance across -40-150℃ temperature range

Complies with EU certification for food-contact materials and can also meet FDA and LFGB standards.

4. Excellent Durability

The highly elastic silicone material quickly returns to its original shape after every dispensing cycle.

Even after thousands of squeezes, the valve maintains:

Stable opening pressure
