Bolted Body Construction As a standard, the valves are manufactured in 2-piece or 3 Piece bolted body designs, where the joint between the body and the connector is bolted. Double Block and Bleed SAP Trunnion Mounted Ball Valves are designed for upstream sealing, so that the double block and bleed features are automatically built in. The load generated by the line fluid on ball is absorbed by the Trunnion bearings and is directly transmitted to the valve body. The valve stem is hence free from any bending load which leads to reduced stem friction torque and enhanced stem seal life. The seat rings are allowed to float in the flow axis against a fixed ball so that the line pressure assists in pressing the spring-loaded upstream seat against the ball. Thus, the operating torque and wear on the seats is relatively low, enhancing seat life. The seats provide the positive seal at both upstream and downstream independently. The fluid is blocked from the body cavity; this facilitates to check the integrity of the upstream and downstream seats.

Lower Torque : There is no frictional contact between disc and rubber seat, which makes frictional resistance almost close to zero, thus markedly reducing operating torque. Low Torque with any fluid : There is no point at which frictional resistance occurs. Therefore, torque is always low regardless of the fluid, air water or Oil. Long Service Life : When the disc contacts the tapered projection of the rubber seat, a complete seal, is attained, which results in long service life. Greater Sealing Capacity : The dynamic seat means the greater pressure and betters the sealing. Bi- directional zero leakage butterfly valve. Accurate Dual stem sealing and Quarter turn operation for excellence flow control. Compact space saving design. Seat integrally moulded with the body. Sturdy & robust construction. Disc assembly perfectly centered & secured in valve Body bore. Flow through disc ensuring minimum pressure drop. Compliance with: IS 13095, AWWA C504, BS 5155 standards.
