Product Description

                                                                                 PTFE CHEVRON V PACKING             

PTFE V-packing, also called vee packing, chevron packing, and parachute packing, made with various Elastomers, and PTFE based materials, and is used in Pumps and Valves to seal the fluid or gas being moved.
Vee Packings in different materials are available.PTFE material has excellent resistance for all chemical corrosion. Its friction coefficient is the lowest in plastics.Temperature changes do not affect its electrical insulation property. So PTFE often be called "plastic king". PTFE is suitable for making corrosion resistant parts, wear parts, seal, insulation parts and medical equipment parts.         

PTFE chevron packing set consists several V-rings and a pressure ring. The V rings are the primary sealing element. When pressurized, it activates the subsequent V-shaped chevron seals, pushing the sealing lips outward.The chevron packing sets are made Of wear-resistant PTFE compounds. The pressure ring typically consists of PEEK. For the sealing requirements Of the Oil and gas market.
The numerous sealing edges generated this way reduce the risk Of leakage. The pressure ring ensures that the sofier PTFE elements are not pushed into the downstream system gap (gap extrusion).

V-Packing or Vee Packing if you prefer is commonly used in valves, reciprocating Pumps, centrifugal pumps, mixers, agitators, and actuators. The industries they are used in include but are not limited to food (PTFE is FDA application compatible), chemical (PTFE has a 0-14 ph range), oil, gas, pulp and paper, water, wastewater, power generation, the list goes on. Many of the PTFE V's we sell go into original equipment manufacturers' products.  

Mixed chevron sealing sets made of PTFE and PTFE-impregnated plastic fabric offer much greater stability under compressive load with lower thermal expansion than chevron sealing sets made of pure PTFE or PTFE compound. Depending on the application and the operating conditions PTFE-impregnated plastic fabric chevron seals can be installed on their own or combined with chevron seals made of pure PTFE or PTFE compound. Here it should be borne in mind that combined chevron sealing sets offer a greater sealing effect due to the sandwiched PTFE chevron seals.

 Range Of Application:

· Valve stems
· Machines with very fast reciprocating movements
· Forgng presses
· lnjection molding machines
· Hydraulics in steel mills
· Marine hydraulics
· Petroleum production
