DN80 DN100 Pph Gear Worm Manual Pph Butterfly Valve

Product Description

The PPH butterfly valve operates by having an actuator drive the valve stem to make a 90 - degree rotation, which in turn drives the disc - shaped valve plate to rotate, achieving the opening and closing of the valve to control the flow and blockage of the medium. It can also be used to regulate the flow rate.

Materials: The valve body and valve plate of the PPH butterfly valve are generally injection - molded from PPH material, which has excellent corrosion resistance, wear resistance, and insulation properties. It is lightweight, facilitating transportation and installation. The valve stem is mostly made of carbon steel or stainless steel, and the sealing materials are commonly EPDM, FPM, etc., which have good sealing performance and chemical corrosion resistance.
 

Connection Mode: The common connection mode is the wafer - type. When installed, the butterfly valve is clamped between two pipeline flanges and connected by bolts. This structure is compact and takes up little space.

 

• Strong Corrosion Resistance: The PPH material can resist the erosion of various chemical substances such as acids, alkalis, and salts, and can be used in the transportation and control of corrosive media in industries such as chemical, petrochemical, and pharmaceutical.
•  
• Good Sealing Performance: The carefully designed sealing structure and high - quality sealing materials ensure that the valve can achieve zero leakage when closed, effectively preventing the leakage of the medium.
•  
• Easy to Operate: It can adopt a variety of control methods such as manual, worm - gear, pneumatic, and electric. The electric drive technology can also achieve remote control and automatic operation, improving the accuracy and efficiency of control.
•  
• Large Flow Capacity: The structure of the butterfly valve results in a small pressure loss when the fluid passes through the valve, and it has a large flow capacity, which can meet the transportation requirements of large flow rates.

 

A PPH butterfly valve works based on a simple yet effective mechanism. Here's a detailed explanation: 

**Actuation**: The valve is equipped with an actuator, which can be of various types such as manual, pneumatic, electric, or hydraulic. When the actuator receives a signal or is operated, it initiates the movement of the valve stem

 **Valve Stem Rotation**: The actuator causes the valve stem to rotate. In the case of a PPH butterfly valve, the valve stem typically rotates 90 degrees from the fully closed position to the fully open position, and vice versa.

 **Valve Plate Movement**: The valve stem is connected to the valve plate. As the stem rotates, it imparts the same rotational motion to the valve plate. The valve plate is a disc - shaped component that is located within the valve body and perpendicular to the flow path of the fluid.

**Flow Control**: In the closed position, the valve plate blocks the flow of the fluid through the valve, preventing any medium from passing. As the valve plate rotates open, the area available for the fluid to flow through gradually increases. The degree of opening of the valve plate determines the flow rate of the fluid. In a fully open position, the valve plate is parallel to the flow direction, allowing the maximum amount of fluid to pass through with minimal resistance. This enables precise control over the flow of fluids in a pipeline system, whether it's for starting, stopping, or regulating the flow of various media such as water, chemicals, or gases.
