Vertical Check Valve

The vertical check valve is an automatic valve specifically designed for vertical pipeline systems. It enables one-way fluid flow via the medium’s pressure and automatically closes during reverse flow to prevent medium backflow. Its core advantages include space efficiency, reliable non-return performance, and low maintenance requirements, making it widely used in the construction, industrial, and energy sectors.

Product Formation

These brass liquid check valves are formed through precision manufacturing. They consist of a solid brass valve body, a precision-machined brass disc, and alloy spring-sealing components. High-quality brass and alloy materials are used, and advanced CNC machining and polishing processes ensure their reliability. Through rational structural design (e.g., a streamlined flow channel and self-sealing disc), they can efficiently block reverse flow while minimizing pressure loss during forward flow, ensuring stable unidirectional liquid movement in fire protection, plumbing, and industrial systems.

Product Features

Vertical installation: Compatible with vertical pipelines, requires no horizontal space, and is suitable for compact scenarios (e.g., pipe shafts, pump outlets).
One-way check: Lift- or swing-type valve discs automatically block medium backflow, with optional soft or metal seals for high reliability.
Low flow resistance: Straight-through flow channels reduce energy consumption; some models are silent and water-hammer resistant.
Wide adaptability: Suitable for various media (e.g., water, steam) for PN1.0–PN42.0 and -20℃–450℃ operating conditions. The valve body is corrosion-resistant and durable.
Easy maintenance: Simple structure with few failures; flange or threaded connections facilitate seal replacement.
