Submersible gate valve

Brand：Pneumatic eccentric butterfly valve 型號：SZ45X-16Q

Submersible gate valve
It mainly consists of submersible motors, enclosed hydraulic systems, bladder type hydraulic breathing apparatus, travel switches, gate valves, etc. It has the characteristics of underwater use and remote control. Without a screw nut rotating motion pair, the linear motion of the oil cylinder has the characteristics of opening force greater than closing force, hydraulic overload protection, etc., to avoid phenomena such as motor blockage, gate wedge and screw top bending.
Connect the power supply to start the gate valve, and the electric motor drives the hydraulic pump to work. The hydraulic pump drives the oil cylinder to perform reciprocating linear motion through a differential hydraulic system, thereby opening and closing the gate valve through the oil cylinder gate valve connection device. When the gate valve is opened to the desired position, the hydraulic system has an overload protection to ensure the safe operation of the gate valve, without causing valve stem bending, gate valve wedging, and other phenomena.

Diving gate valve product information
Submersible Gate Valve is a type of valve designed specifically for underwater or humid environments, commonly used in water engineering, sewage treatment, underground pipeline networks, and other scenarios. Its core features are waterproof sealing and corrosion resistance, and some models support remote control or automatic opening and closing functions.
Main types and parameters
Classified by structure:
Bright stem type: The valve stem is exposed for easy observation of the opening and closing status, suitable for shallow water or frequent maintenance scenarios.
Concealed stem type: The valve stem is built-in, with a compact structure, suitable for deep water or confined space environments.
Key parameters:
Nominal pressure: 1.6-16MPa (conventional model).
Applicable media: water, sewage, and fluid containing particles.
Valve body material: ductile iron (corrosion-resistant), stainless steel (high-pressure environment).
Connection methods: flange connection (mainstream), groove type (quick installation).
Application scenarios and product examples
Municipal engineering:
Underground gate valves (such as SZ45X-16Q) are used for water pipelines and support direct burial installation with an extended valve stem design.
