PTFE Lined Ball Valve

We offer Gear Operated Ball Valve.

Construction of Material:

Casting Material Specifications:

• Cast Iron : IS 210, G.R.F. G.200
• Ductile Iron : ASTM A395
• Cast Steel: ASTM A216, G.R. WCB
• S. S. 304 : ASTM A351 CF8
• S. S. 304L : ASTM A351 CF3
• S. S. 316 : ASTM A351 CF8M
• S. S. 316L : ASTM A351 CF3M
• Alloy 20 : ASTM A351 CN7M

Design Standard:

• Ball Valve, 2 Pieces    : BS 5351, Short / Long Pattern
• Ball Valve, 3 Pieces    : BS 5351, Long Pattern

Standard Resin Specifications:

• PFA       :   ASTM D 3418
• FEP       :   ASTM D 2116

Service Temperature:
PFA:

• Maximum continuous service temperature    :   265° C
• Melt point:   305° C

FEP:

• Maximum continuous service temperature    :   200° C
• Melt point : 260° C

Lining Thickness: 

• Minimum Lining thickness would be 3.0 mm over all wetted portion

Chemical Inertness:

• PFA/ FEP is chemically inert to most of the all chemicals and solvents with the exception of molten alkali metals
• PFA / FEP lined valves are used to convey, and are inert to, these chemicals : All acids including hydrofluoric, sulphuric and aqua regia, all caustic, all chlorides organic and inorganic, all solvents, all bleach solutions, all peroxides, all phenols and any combinations of above materials
• Combined with the chemical inertness of PFA / FEP is its unique non-stick property. Thus a PFA / FEP lined products eliminate or minimize the built up of deposits of the products which otherwise reduce flow and affect processing operations.     
• PFA / FEP Lined Ball Valves Finish
• The interior surface of all valves are clean and free of mold burrs, rust, scale or others that may adversely affect the performance of lining.
• The exterior surface of all valve bodies are be cleaned by sand / shot blasting and painted by 1 coat of Epoxy primer and 2 coats of Polyurethane Top coat.

Products Inspection and Testing :-

Hydrostatic Pressure:

• Body Test   : 10 Kg/Cm2
• Seat Test    : 10 Kg/Cm2
• (Hydrostatic pressure at room temperature using clean water.)

Electrostatic Pressure:

• Non-destructive high-voltage test at an output voltage of 10,000 V. When electric contact is made, a visible/ audible spark or both occur at the probe if there is any defect in lining.

Visual Inspection:

• All surfaces are free from blister, porosity or any other defect. All checks / tests are conducted before shipment.

Storage & Transport:

• Each end of valve is protected by specially made rubber cap so that products are capable to withstand normal handling during transport
• All the materials are supplied with export wooden case or card box packing depending upon the weight and mode of shipment

We offer Gear Ball valve. A Gear Ball Valve is a type of valve in which the spherical disc controls the flow through it. The hole of the sphere is positioned to offer apt flow through the valve.

The handle of the valve is in line with the position of the hole or port to enable smooth functioning. We offer a wide range of Ball Valve that is manufactured from graded raw material like steel, and is in accordance with the current market trends.

We offer a wide range of PTFE Lined Ball Valve and as per ANSI, DIN and JIS standard. Available in sizes from 15 NB (1/2" NB) to 300 NB (12" NB). These are manufactured using high quality corrosion resistant material which makes suitable for controlling complex materials.

 

Types of PTFE Lined Ball Valve:

• Two Piece (As per BS 5351, Short pattern)
• Three Piece (As per BS 5351, Long  pattern)
