II. Structure and Technical Features
Main structure: The valve structure is similar to that of a globe valve, consisting of the valve body, valve cover, valve disc, etc. The valve disc opens under the thrust of the medium, and automatically closes when the medium flows back under the action of its own weight and reverse pressure.
Connection method: Threaded (internal thread) connection is adopted. Common thread types include G, NPT, BSPT, BSP DIN259/2999, etc., suitable for small-diameter pipelines.
Product features:
Simple and compact structure, small volume, light weight.
The valve seat usually adopts an elastic sealing structure, opening and closing are light, and the sealing is reliable.
The flow channel is designed smoothly, the fluid resistance is small, and the valve disc can open under a smaller pressure difference. Easy to maintain. The sealing rings and other consumable parts are usually designed to be movable, making them easy to disassemble and replace.

The H11T/W cast iron internal thread lift-and-close check valve is an automatic valve that automatically opens and closes based on the flow of the medium itself, and is used to prevent the backflow of medium in the pipeline. It is also known as a one-way valve or a reverse flow valve. This valve is a lift type check valve. Its valve disc moves up and down along the center line of the valve seat channel. It is usually installed horizontally on the pipeline.
It is widely used in pipeline systems of industries such as building water supply, heating, petrochemicals, energy and power.This valve is suitable for preventing the backflow of water, steam, oil and other media in pipelines. It is widely used in pipeline systems of industries such as building water supply, heating, petrochemicals, energy and power.
