Cast Iron Hydraulic Control Valve

Cast Iron Hydraulic Control Valve The cast iron hydraulic control valve is designed to regulate the flow of water efficiently. When water enters from the inlet, it flows through the valve into the main valve control chamber. When the solenoid pilot valve opens, the water in the control chamber is released through the solenoid pilot valve, allowing the ball valve to discharge. The valve opening is larger than that of a needle valve, causing the pressure in the main valve control chamber to drop significantly, which keeps the main valve fully open. When the solenoid valve is closed, the water in the control chamber cannot drain out, leading to an increase in pressure. This pressure pushes the diaphragm, closing the main valve. **Material Composition of Water Flow Control Valve Parts:** | Part Name | Material | |-------------------|-----------------| | Body & Cap | Ductile Iron | | Valve Seat & Disc | Brass | | Valve Stem | Stainless Steel | | Spring | Stainless Steel | | Surface Coating | EPOXY | | Valve Sealing | EPDM/NBR | **Performance Specifications of Water Flow Control Valve:** | Normal Pressure (MPa) | Body Test Pressure (MPa) | Sealing Test Pressure (MPa) | Applicable Medium | Applicable Temperature (°C) | |-----------------------|---------------------------|------------------------------|-------------------|-------------------------------| | 1.0 | 1.5 | 1.1 | Water | 0–80 | | 1.6 | 2.4 | 1.76 | | | | 2.5 | 3.75 | 2.75 | | | This valve is ideal for industrial and commercial applications where precise flow control is required. It features a durable construction with high-quality materials ensuring long-lasting performance. The epoxy coating provides excellent corrosion resistance, while the EPDM/NBR seals ensure reliable sealing under various conditions. The valve is packaged in seaworthy packaging, making it suitable for international shipping. Originating from Tianjin, China, it meets international standards such as ASTM, ANSI, DIN, and JIS. With a model number of DN50-350 and an outer diameter range of DN15-350, this hydraulic control valve is a versatile solution for water flow regulation systems.

Bike

The bicycle was introduced in Europe in the 19th century and is still a very important means of transport today, and has been constantly changing, with more and more options in terms of appearance, function and material, such for convenient travel there are basic pedal Single Speed Bicycle, road bikes, electric bikes, for wilderness riding Sports Bike, there are mountain bikes(mtb bikes), snow bikes, for bicycle performance use there are Track Bicycle, bmx bikes and many more.
Our company mainly produced Single Speed Bikes, in order to the high strength and low weight, we adopted the aluminum alloy frame, that will lighter than steel frame and have very good rigidity and toughness at the same time.
The aluminum alloy frame and carbon fiber fork better suited to the flat road, potholed country road and bicycle race scene.
