An adjustable gland box type shaft sealing arrangement permits on line adjustment of the packing to ensure zero leakage. C 70 80 80 80No. They shall be cleaned out to sound metal before welding, and shall be submitted to the purchasers inspector for approval in this condition, after which they may be welded if the purchaser so agrees. The valve has a fully rubber lined body and a rubber encapsulated disc with a square slot for the drive end shaft.

SIZE10 15 20 2. The PTFE seat liner covers the entire wetted surface of the body and extends on to the flange contact faces, thus eliminating possibility of any media contact with the body metal. NOTE 2 – The minimum tensile strength been specified in the relevant specifications. However, a quality factor of 0. When the welding of defects is permitted, the welding rod shall be such as to produce a weld having characteristics similar to the parent metal. The top shaft sealing is through stuffing box type gland sealing arrangement, which is field adjustable.

All dimensions in millimctres. The double offset disc design nearly eliminates the seating wear due to the camming action of the disc during closing. This general purpose soft seated Butterfly valve has a fully rubber lined single piece body with centric disc construction and is available in wafer type body pattern.

Flanges not integral Machined at Back. For details reference may be made to IS: Use this table vlanges for nominal sizes flantes to 65 mm for 1. Intervalve’s GKL series valves are designed to meet the demanding requirements of the general utility valve market with the HVAC segment in particular. The valve has excellent throttling characteristics with good low flow control capability, which offers an inherently higher rangeability.

The disc has a spherical profile and comes out of contact with seat in the initial opening f,anges. A real workhorse from the IV stables, IVGK model Butterfly valve incorporates the optimum design features to provide long trouble free service in the field.

The fully circular back up elastomer and live loaded disc shoulder sealing ensures bubble tight closing of the Valve with zero shaft leakage. These shall Abe screwed in 6 shall as agreed be prepared theto iis. The thickness of the portion of the flange which connects it to the pipe should be not less than the pipe thickness nor more than 3 mm thicker.

The lightweight construction with the narrow wafer body enables easy fitment of these valves in ducts, manifolds and exhaust lines without additional support or strengthening of pipe lines.

Yet another real workhorse from the IV stables, IVTL model Butterfly valve incorporates the optimum design features to provide long trouble free service in the field. The mechanical stopper provided on the valve body ensures precise valve closing every time to ensure specified seat tightness.

The integrally moulded spherical profile seat with a matching profile on the disc shoulder both closed die moulded ensures perfect sealing with minimum operating torque and prevents any fluid ingress into the shaft bores.
