Micro flow pneumatic diaphragm single-seated regulating valve
Low-flow thin film single-seat regulating valves can widely control the flow of various gases, liquids, and steam, ensuring the normal operation of the production process. This series of products has a wide range of applications, with pressure levels ranging from 1.6 MPa to 11.0 MPa. The rated flow coefficient Kv is much smaller, with a minimum of 4x10⁻⁶, so it can be used in many occasions requiring precise control of micro-flow, such as fine chemicals, food additives, pharmaceuticals, and electronics industries.

1. Diaphragm cover 2. Diaphragm 3. Spring 4. Push rod 5. Bracket 6. Stem 7. Bonnet (standard type) (normal temperature type) 8. Valve core 9. Valve body
This product consists of two parts: a multi-spring pneumatic diaphragm actuator and a plunger-type single-seated control valve. The actuator receives external control signals, the push rod generates displacement, and the stem 6 and valve core 8 move relative to the valve seat, changing the fluid flow entering the valve body 9, thereby ensuring that the production process proceeds normally according to a certain procedure or requirements.
Features:
The valve body flow path is strictly designed according to the equal cross-section and low flow resistance, so the pressure drop loss is small. The valve core adopts a reinforced stem single-guiding structure, with excellent operational stability and can withstand the impact of high-speed fluid on the valve core. The actuator adopts a multi-spring circular uniform arrangement and uses a high-strength rubber diaphragm actuator, which can accept control signals with different values such as 20-100 KPa, 40-200 KPa, and 80-240 KPa.
