Grooved Non-rising Stem Soft Seal Visibility Gate Valve

This valve is an upgrade from conventional valves with the addition of an opening indicator function. It is mainly used to connect or shut off the medium in the pipeline. The valve stem performs a rotational movement, and its transmission thread is located inside the body cavity, which saves installation space. The gate is fully rubber-coated; by utilizing the elastic deformation of rubber, the valve achieves a tight fit when closed, resulting in excellent sealing performance and thus zero leakage. There is no gate slot in the valve cavity, preventing the retention of debris, which minimizes fluid resistance and makes opening and closing operations lighter.

Product Parameters

Size range:	2"-20" (DN50-DN300)
Design standards:	ISO 6182
Working pressure:	PN10	PN16	PN25

Product Features

Low operating torque function

The valve can be easily closed with a torque of 80% of the nominal diameter, achieving zeroleakage under nominal pressure.

Rust-proof function

The bonnet and gland adopt countersunk wax-sealing design, with no exposed bolts, completely solving the problem of bolt rusting.

Anti-external leakage function

The upper seal features a 3-0-ring design to ensure no dripping during the dynamic movement ofthe valve stem; the middle flange adopts a self-sealing design, with the gasket utilizing the O-ringprinciple. The greater the pressure in the valve cavity, the tighter the rubber is compressed,resulting in more reliable sealing.

Anti-internal leakage functio

The gate plate adopts advanced dual-mode glue injection molding and high-temperaturevulcanization processes. The rubber surface of the gate plate has no exposed positioning points.with 100% full coverage. The rubber is evenly distributed, the dimensions are stable, and thesealing performance is excellent.

Product Advantages

Energy conservation and environmental protection

The surface treatment adopts non-toxic epoxy resin powder, which is sprayed by an automatic plastic spraying line to ensure the thickness, continuity and uniformity of the plastic layer.

Excellent material quality

All ductile iron castings are independently cast using domestically leading wire-feeding nodulization technology, with a nodularity rate of over 90%, and quality requirements exceeding national standards.

Low flow loss

Full passage design results in low flow loss, energy saving and consumption reduction.

Low torque

Under the rated working pressure, the opening and closing torque is no higher than 80% of the requirements of national standards.

Reliable sealing

The gate is produced using advanced glue injection vulcanization technology, featuring uniform rubber thickness without exposure, 100% full coverage, and stable dimensions; the upper seal adopts a design of 3 O-rings plus 1 dust-proof ring, ensuring reliable sealing performance.
