Hydraulically Controlled Slow Closing Check Valve Product Introduction
Product Overview:
The Hydraulically Controlled Slow Closing Check Valve is designed to prevent backflow and manage pressure surges. This valve includes both weight-operated and energy-storing types. It can replace two types of valves: a check valve and a gate valve. This versatile valve is ideal for large-diameter pump outlets. It operates effectively within a nominal pressure range of ≤4.0 MPa. The valve features intelligent control capabilities. It allows for both fast and slow closing operations. The closing speed is adjustable.
Structure and Features:
– Dual Types: The valve comes in two types: weight-operated and energy-storing. This provides flexibility for different needs.
– Replacement Capability: It combines the functions of a check valve and a gate valve into one unit. This simplifies system design and reduces the need for multiple valves.
– Hydraulic Control Mechanism: The valve features a hydraulic control system. This system manages the closing speed, allowing for precise control.
– Adjustable Closing Speed: The valve’s closing speed can be adjusted. This helps to minimize water hammer and protect the pipeline system.
– Intelligent Control: The valve supports intelligent control features. This enables automated operation and integration with advanced control systems.
– Durable Materials: The valve is made from high-quality materials, such as stainless steel or ductile iron. These materials ensure durability and resistance to corrosion and wear.
– Compact Design: Despite its functionality, the valve’s design is compact. This makes it suitable for installation in confined spaces.
