The APV Department was founded in 1910 by Richard Seligman, and APV plate heat exchanger is the world's inventor of plate heat exchangers. For a long time, APV plate heat exchanger research has been at the forefront of the world. In addition to the research and development of fluid flow and heat transfer efficiency, APV pays more attention to the study of the convenient operation and maintenance of plate heat exchangers and the longevity of plate gaskets. APV plate heat exchanger plate and gasket characteristics, gasket materials are EPDM, NBR, HNBR, FKM/VITON, etc. The plates include stainless steel AISI304/316/316L/317L, 254SMO/654SMO/904L, Hastelloy, nickel alloy Nickel201, titanium Ti Gr1, titanium palladium alloy and other materials are suitable for various fluid conditions.
Principle of APV heat exchanger:
The basic concept of the plate heat exchanger is that two streams of liquid flow on one side of a thin corrugated metal plate, and heat is easily transferred between the two streams of liquid. Plate heat exchangers occupy less space and are light in weight compared with other heat exchange equipment.
As the world's leading plate heat exchanger plate manufacturer and seller, Baode has a wide variety of domestic plate heat exchanger plates, more models! It can provide all common types of plate heat exchanger plates from well-known brands at home and abroad (including: AlfaLaval /GEA, TRANTER, SONDEX/HISAKA/APV/Thermowave /Schmidt/FUNKE/VICARB/LHE, etc.).

The throttle valve is designed with two plates made from specially molded tungsten carbide materials, which provide exceptional resistance to erosion. By rotating one plate, the orifice can be adjusted relative to the other two holes on the adjacent plate, allowing precise control over the flow of liquids or gases.
This high-performance valve is widely used in drilling, fracturing, mud circulation, and surface high-pressure gas injection systems. One of its most notable features is the ability to maintain a tight seal when closed. The pressure difference between the inlet and outlet forces the two plates together, ensuring a secure closure. In case of sudden pressure surges or unexpected drops due to leaks, the valve can automatically shut down based on pre-set signals from high and low-pressure sensors, significantly reducing the risk of accidents.
Compared to other types of throttling valves, this design offers the longest service life and superior resistance to wear and erosion. Its unique construction ensures reliable performance even under harsh conditions.
Key Features:
- **Unique Plate Design**: The orifice is manufactured using special molded tungsten carbide, and the opening size is adjusted by rotating the stem using a diamond grinding wheel.
- **Effective Sealing**: The fully closed position is designed with a 17° overlap to ensure a tight seal, maintaining performance even after wear and during pressure surges.
- **Tungsten Carbide Wear-Resistant Lining**: A wear-resistant coating is applied to the bushing, enhancing durability and suitability for corrosive environments and high-impact fluid flows, especially in negative pressure drilling operations.
- **Versatile Operation**: Suitable for both land and offshore applications, and can be operated manually or remotely.
Whether you're working in challenging drilling environments or need reliable high-pressure control systems, this throttle manifold provides the durability, precision, and safety you need. It's an essential component for any operation requiring efficient flow regulation and long-term performance.
