Products Decription:

1. The lined butterfly valves bi-directional flow is possible at maxmium operating pressure. Since the valve port corresponds to the piping diameter, a high flow capacity is guaranteed.

2. It features ease of maintenance, repeatable on-off, long life durability.

3. The concentric design is commonly used in the power generation, brewing, water and food industries and suitable for both gaseous and liquid service. Typically applied in chemical/petrochemical process, food and beverage, and pulp and paper etc.

4. Lining material: PTFE, PFA, FEP, GXPO etc.

5. Connection type: wafer, flange, lug etc.

6. Operation methods: manual, worm gear, electric, pneumatic and hydraulic actuator.

7. Youfumi lined three-way ball valves are available as per the needs of applications in additional sizes and other than standard materials.

Single-piece disc/stem unit optionally fluoroplastic
Lined with pure PFA for maximum corrosion resistance and a long service life.Very low friction values and torques during opening and closing due
to the combination of a PFA disc/stem unit with a PTFE body
Optionally antistatic PFA-L
Disc/stem core made of highly torsion resistant Duplex stainless steel 1.4517/CD-4 MCu(18“-40“/DN 450-1000: SS 1.4435/316L)
Alternatively metallic
Made of precision cast stainless steel Polished sealing surfaces, therefore very low friction values
Polished disc surfaces on request
Other materials on request, e.g. Hastelloy® C, titanium
Thick-walled PTFE and TFM-PTFE lining of the valve body
TFM-PTFE lining (2“-16“/DN 50-400 with PFA-lined disc: PTFE as standard, optionally TFM-PTFE)
Lining thickness 0.12- 0.15“ (3 -3.5 mm)
High permeation resistance
Optionally antistatic PTFE-L, PE-UHMW
Wide sealing surfaces of body
lining for reliable sealing even with mating flanges with large radii, e.g. glass-lined components.
Permanently elastic seal in the valve opening by means of silicone insert under the PTFE body lining.
Optionally FKM insert (e.g. Viton®) for use with chlorine gas for example.
Double-action, maintenancefree and self-adjusting top and bottom
stem sealing
therefore reliable even with many switching cycles and fluctuating temperatures:
primary: body lining against disc/stem shoulder
secondary: O-ring PTFE, optionally RPTFE.
Long valve neck
permits optimal heat insulation without the installation of an elevated lever, additional stem extensions on request.
External corrosion protection
Epoxy coating, nuts and bolts made of stainless steel.
Centering to ISO 5211
Chlorine electrolysis options
Specially for use with wet chlorine gas:
Elastic insert made of Viton instead of silicone Body lining made of particularly
permeation-proof, modified PTFE instead of standard PTFE Body nuts and bolts made of steel, for example, instead of stainless steel Tantalum-coated ductile iron body.
Safety stuffing box
for use with environmentally hazardous media, independent action, can be adjusted manually from outside, on request with monitoring
Manual actuation with limit switch
