Definition of High-Flow Backpressure Valve

High-flow backpressure valves are specifically designed for industrial-grade fluid control systems. Adopting a piston-type pressure transmission structure, they can stably maintain the upstream pressure within the range of 01500 Psig, and are suitable for pipelines conveying corrosive media, high-purity liquids, and gases. The valve body is electropolished to achieve a surface roughness of Ra ≤ 0.4μm.

Technical Parameters of High-Flow Backpressure Valve

The piston sensing design enables better pressure control of the system before the inlet of the backpressure valve.

The large-diameter piston enhances pressure sensitivity.

Applicable to both gases and liquids.

The piston-type design features a compact structure.

Body material: 316L stainless steel.

Panel mounting option is available.

Maximum Operating Temperature: 260°C.

Pressure Range: 03000 psig.

Flow Coefficient (Cv): 1.0.

Weight (Backpressure Valve Only): ≈1.55 kg.

Design Features of High-Flow Backpressure Valve

1. Precise Pressure Control

Adopts diaphragm pressure transmission technology, featuring fast response and high control accuracy.

Equipped with external pressure feedback and an extra-large diaphragm design, supporting pressure adjustment to zero differential pressure.

2. Corrosion Resistance and Sealing Performance

The valve body is electropolished (surface finish: 25 Ra). Diaphragm options include PTFE or nylon-lined viton, ensuring excellent chemical corrosion resistance.

The balanced valve seat combined with a sealing rib structure eliminates leakage.

3. Easy Maintenance

Supports inline CIP (Clean-in-Place) cleaning.

Diaphragms or O-rings can be replaced without disassembling the valve.
