PTFE or PFA lined control valves with even thickness without cavities.

Lined valves by Pfeiffer combine the excellent mechanical properties of metallic bodies with the corrosion resistance of fluorocarbons, such as PFA and PTFE.

PFA lined globe control valve

Pfeiffer 1b PFA lined globe control valve is designed for general service applications up to ANSI 150. This applications focus on highly corrosive media found in chemical processes.

Pfeiffer 1b can be assembled with a pneumatic, electric, hydraulic or electrohydraulic actuator offered by SAMSON as well for completion of the control valve. These control valves are designed according to modular mounting principle; they can be equipped with SAMSON GROUP actuators and valve accessories such as positioners, limit switches and solenoid valves.

Segmented Ball and Ball Valve

Cera System offers wear and corrosion resistant ball valves for open / close and control applicaction.

Ball Valve • KST

Ball valve lined with ceramics for open/close and control function resistant to wear, corrosion, high pressure and temperatures.

Common applications

• Thermal power plant (coal operated)
  Fuel gas desulfurization plant, lyme milk, gypsum slurry, high chloride process water and solids.

• Steel Plants
  Pulverized coal injection (PCI), Electric arc furnace (EAF), desulphurization of pig iron.

• Residue incineration plants
  HCL pre-washers, lime milk suspension for pH regeneration, low pH washing water injection (corrosive)

• Pulp and Paper Plants
  Ink área, kaolin, bentonite, loads, dyes, bleachers, powder, cellulose residues, lyme milk, MgO2, green liquor, wooden particles in suspension.

• Copper Mining
  Copper concentrate pulp (flotation), pneumatic transport of pulverized copper concentrate to smelting.

Wear and corrosion resistant disc valve

Wear and corrosion resistant disc valves for open/close and control function. With this type of construction, the fluid runs through ceramic only.

Disc Valve-SVC parallel 4-gate valve

The SVC-type valve is a disc slide valve with a ceramic sealing system for open/close function and control tasks, for use in highly corrosive and extremely abrasive media. It is designed for extreme conditions, where either high switching frequencies and a long service life are required, or where severe abrasion occurs in the control position but dead space cannot be permitted inside the valve.

• OPTIONS

• With compression gland packing

• With sealing gas connection

• Various ceramics and sealing materials

Typical application areas

• Iron and steel
  Crude iron desulphurizaton (additives supply: CaC, Mg…)

• Chemical industry
  Alternative to PTFE/PFA-lined valves, where medium is abrasive and/or tends to diffusion.
