1/2" - 4" CF8M 1 PC Stainless Steel Ball Valve Low Pressure Reduced Port
1 Description:
Ball valves are designed with extensive safety considerations for users, Blow-out proof stems, provision of locking devices and prevention of misalignment of lever handles provide safe handling in the field and trouble-free operation in the plant. Antistatic devices, firesafe seal design and cavity pressure relief features all assure the economic benefits of smooth, steady plant operation.Series provides the convenience of very easy maintenance critically required for process plants.

4 Feature Advantage:
ball valves are furnished, as the manufacturer’s standard,
with ball seats made of denatured PTFE, a molecularly reinforced PTFE copolymer, and specially
engineered for high performance which include:
Wide service temperature range of -29°C (-20°F) trough 270°C (518°F) SCTDZ/UTDZM.
This is for standard valve design and materials used for medium to high temperature services. The lower temperature range can be extended down to -196°C (-321°F) by means of extended bonnet design and special low temperature service materials.
1. High chemical resistance is comparable to virgin PTFE
2. Monomer permeability is lower than other PTFE materials.
3. Resistance against compression and creeping (cold flow) is
higher than other PTFE materials to guarantee long life cycle.
4. Specific gravity and friction coefficient are equal to those of virgin PTFE for smooth valve operation.
5. Purity of processed products is guaranteed as highly as virgin PTFE.
6. Resiliency is as high as other PTFE materials for bubble- tight sealing performance.
