ZZVP self-acting micro-pressure regulating valve

ZZVP self-acting micro-pressure regulating valve is an actuator product that does not require external energy. Can be used for nominal pressure PN0.1, PN10. Micro pressure can be adjusted in stages. From 50mm water column to 0.1MPa. It is widely used in industrial combustion systems to control two materials, such as gas, air flow ratio, to Up to ideal combustion. Used for sealing oil-based seals of hydrogen-cooled generator sets. When the low-pressure end of the differential pressure valve is open to the atmosphere, it is a micro-pressure valve (negative pressure of the differential pressure valve, end pressure, and zero force).

Basic design: GB / T 17213.1
Test: ASME B16.104

Specifications

Product model: ZZVP
Size range: DN15 ~ DN100
Pressure level: 0.1 ~ 1.0MPa
Housing material: carbon steel, stainless steel
Applicable medium: gas
ZZVP, ZZCP self-operating differential (micro) pressure regulating valve is an energy-saving product that does not require external energy. The pressure change of the medium in the process pipeline is compared with the signal to balance the force of the medium being adjusted with the output force of the actuator. To achieve stable pressure and differential pressure.
ZZCP-1 differential pressure valve adopts balanced single seat valve, which has stable pressure, high precision and good tightness, and is used to control small differential pressure. The ZZCN-10 differential pressure valve uses a double seat valve with a large flow coefficient. The valve core is mounted upside down and upside down to form two different products. This product is suitable for various industrial furnace combustion systems to control the flow rate of the mixture of two fuel gases or used in the sealing oil system of hydrogen-cooled generator sets. At the same time, it can also be used for the automatic decompression, stabilization or pressure relief of various industrial gases. control.
ZZV type micro pressure valve adopts balanced single-seat valve, which can adjust the set value arbitrarily during operation. Therefore, it is suitable for micro-pressure automatic adjustment of various industrial furnace combustion system fuel gas, petroleum work in progress, or storage tank storage gas and heat treatment protection gas.
