Pneumatic Bellows Lined With Fluorine Control Valve

Pneumatic Bellows Lined With Fluorine Control Valve

ZJHPF pneumatic fluorine lined single seat regulating valve is composed of multi-spring pneumatic film actuator and anticorrosive through low flow resistance single seat valve. In contact with the fluid body inner wall and valve components are using high temperature molding lined with fluorine plastic process, coated with a layer of polyperfluorinated ethylene propylene (F46), polytetrafluoroethylene (PTFE), soluble polytetrafluoroethylene (PFA) and other anti-corrosion materials, can completely cut off the corrosive medium and body shell contact, with good sealing performance,, the fluid channel in an s-shaped streamline and small pressure drop loss, large capacity of valve, flow characteristic accurately, with electricity and gas valve positioning or pneumatic valve positioner, can realize to control the process of the pipeline automatic adjustment, widely applicable to strong corrosive medium such as acid, alkali and toxic, volatile, easy penetration control of gas and liquid medium.

ZJHPF pneumatic fluorine lined single seat bellows regulating valve in addition to the function of ZJHPF, also increase the sealing structure of ptfe bellows, can better meet the sealing performance, can achieve multiple sealing protection, reject media leakage, for demanding media (chlorine gas and other highly toxic and strong corrosion) have a better sealing guarantee effect.

Key Features & Benefits

• 100% hermetic sealing prevents fugitive emissions (compliant with ISO 15848-1, TA-Luft).
• PTFE, PFA, or ETFE lining resists acids, alkalis, solvents, and ultra-pure media.

• 4-20mA, HART, or Fieldbus communication for seamless DCS/PLC integration.
• Spring-return or double-acting options for fail-safe operation.

• Electropolished internals (Ra ≤ 0.4 µm) for semiconductor-grade purity (SEMI F20 compliant).
• No dead zones or crevices to prevent particle accumulation.

• Resistant to HF, HCl, HNO₃, aqua regia, and chlorine gas.
• -50°C to 200°C (-58°F to 392°F) operational range.

• Bellows design eliminates stem leakage, reducing maintenance costs.
• Modular construction for easy disassembly and cleaning.
