The closing member of a stainless steel flanged globe valve is a plug-shaped valve disc with a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the valve seat. The valve stem movement type is commonly referred to as a “hidden stem,” while there is also a lifting and rotating stem type, commonly referred to as an “exposed stem.” A globe valve is a type of valve where the closing member (valve disc) moves along the centerline of the valve seat.

A fluorine-lined stop valve is a type of valve in which the closing member (disc) is driven by a valve stem and moves up and down along the center axis of the valve seat. It is a commonly used shut-off valve, mainly used to connect or shut off the medium in a pipeline, and is generally not used to regulate flow.

Double eccentric butterfly valve, also called high performance butterfly valve, is further improved on the basis of single eccentric butterfly valve, its structural characteristics of the butterfly plate rotary axis (i.e., stem axis) and butterfly plate sealing cross-section offset by one size, and with the valve body channel axis offset by one size. Compared with the centerline butterfly valve, the effect of double eccentricity makes the valve open and the butterfly plate can be quickly separated from the valve seat, greatly eliminating the unnecessary excessive squeezing and scraping phenomenon between the butterfly plate and the valve seat, reducing the opening torque, lowering the wear and tear, and improving the life of the valve seat.

ZZYP type self-operated pressure regulating valve does not require any external energy, the use of the regulated medium itself to regulate the actuator products.

When the medium flows in the specified direction, the valve is opened by the force of the medium: when the medium flows backward, the sealing surface of the valve and the valve seat is closed due to the self-weight of the valve and the role of the valve and the valve by the reverse force of the medium, to prevent the medium from flowing backward.

Counterclamp check valves are also known as backflow valves, backstop valves, backpressure valves, check valves. These valves are automatically opened and closed by the force generated by the flow of the medium itself in the pipeline.
