Technical details and manufacturing context for Poppet/Seal Assembly

Definition

The Poppet/Seal Assembly is a component used in rapid-activation valve banks, where it provides sealing and flow control. It consists of a poppet (valve disc) that moves against a seat to regulate media flow, and integrated sealing elements that ensure a tight closure under varying pressures and temperatures. The assembly is designed for applications requiring rapid opening and closing cycles, such as in industrial machinery and equipment manufacturing. It is available with materials including stainless steel, PTFE, nitrile rubber, and polyurethane, and is specified by parameters such as operating pressure (1.0–1.6 MPa), flow coefficient (Cv 0.8–1.2), leakage rate (≤0.01 mL/min at rated pressure, class VI shutoff), operating temperature (-40–85 °C), response time (≤10 ms), cycle life (≥1,000,000 cycles), seat diameter (10–25 mm), stroke length (2–5 mm), seal hardness (70–90 Shore A per ISO 7619-1), seal material (NBR/FKM/EPDM), body material (SS304/SS316 per ASTM A276), and weight (0.05–0.2 kg). These values are reference ranges and must be confirmed for the specific model and application. The assembly operates through axial movement of the poppet; when actuated, it lifts to allow flow, and when closed, it creates a seal. The integrated sealing elements provide additional sealing force and compensate for wear, ensuring leak-tight performance during rapid cycling. For procurement, verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The assembly operates through axial movement of the poppet against a valve seat. When actuated, the poppet lifts from the seat to allow media flow; when closed, it returns to create a seal. The integrated sealing elements (such as O-rings, gaskets, or custom seals) provide additional sealing force and compensate for wear, ensuring leak-tight performance even during rapid cycling.

Frequently Asked Questions

What is the operating pressure range for this assembly?

The reference operating pressure range is 1.0–1.6 MPa. Confirm the exact range for your specific model and application.

What materials are available for the poppet and seals?

Materials on file include stainless steel, PTFE, nitrile rubber, and polyurethane. Seal material options include NBR, FKM, and EPDM, selected based on fluid compatibility. Body material options are SS304 or SS316 per ASTM A276.

What is the leakage rate at rated pressure?

The leakage rate is ≤0.01 mL/min at rated pressure, achieving class VI shutoff. This ensures tight sealing under rated conditions.

How long is the cycle life?

The cycle life is ≥1,000,000 cycles under rated conditions. This is a reference value; actual life may vary with operating conditions and maintenance.
