DESIGN FEATURES AND APPLICATIONS

SCV’s standard ball valves have been design to API highest standards. Complete Split body & Fully welded design offers maximum protection against line pressure and thermal distortion with long life and trouble-free performance. SCV is supplying its products to the Crude oil transport and processing, Power engineering, Water supply systems and Process Industries.
1. Seal Feature SCV ball valves are produced with spring-loaded seats. This spring load keeps the seat in contact with the ball even in absence of line pressure and makes very efficient seal at low line pressure.As line pressure increases, the seat area creates a piston effect which forces the seat against the ball, therefore a tight seal becomes effective. If the pressure is higher, the force exerted by the seat on the ball is increased by action of the pipeline pressure. Therefore, the higher the line pressure, the greater the piston action.Seats are available in PTFE, R-PTFE, NYLON or others. 2. Self Lubrication Self lubrication, low friction PTFE is used for stem bearings, stem seals, and body seats. NYLON or other low friction materials are used for seat inserts. Self lubricating seals and stem bearing give predictable operating torque for the life of the valve. 3. Fire Safe Construction with Secondary Metal Seat SCV’s ball valves have been fire tested and can be supplied to API RP6F and API 607. The soft seat inserts, irrespective of their materials, will possibly fail when subjected to sudden high temperature conditions. We provide fire-safe design which may substantially prevent leakages through seals when damaged by high temperature. The function of the seats before and after the fire test is shown on the sketches. If the seat inserts are destroyed or burned out, a metal to metal seal is formed between the lower diameter of the seat and ball, while the seat to body seals, the stem packing and the end connections to body seals are designed to resist high temperature and will remain undamaged. *(See Figures 1 & 2)*
4. Trunnion Mounting Trunnion mounted stems absorb the thrust from line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure, operating torque stays low. *(See Figure 3)*
5. Body Vent and Drain The body cavity may be vented in both open and closed state. *(See Figure 4)*
6. Double Block and Bleed The seats are of both-side-sealing type, which means that they seal both on the upstream or downstream side of the ball valve and inside the valve. Whether in the open or closed position, pressure on each side of the ball is blocked from the body cavity by the seat rings engineered to self relieve. No pressure build up can occur in to body cavity. The body cavity can than be vented to the atmosphere or drained through the body port. *(See Figure 5)*
7. Sealant Fitting Upon request, sealant lubrication fittings are installed. In the event of seat insert or stem seal damage, external or internal leakage can occur. Emergency sealant injection can save the integrity of the valve by incorporating a sealant seal around the stem or between the seat and the ball until such time the valve may be properly serviced. (See Figures 6, 7 & 8)
8. Antistatic Device The springs provided at the stem allow the static charges to be led to the piping. In this way, an electrostatic charging of the ball is eliminated. *(See Figure 9)* 9. Stem Seal with Blow-out Proof Stem The stem is independent of the ball and is a blow-out proof design. As an integral part, a stem has a flange at its lower side. Owing to such a specific design, the stem flange prevents the stem from blowingout. This feature also allows replacement of stem packing while the valve is under pressure.The torque is transmitted to the ball by generously proportioned mating joint, hence the stem is not affected by the side thrust.

BALL VALVE FLOW COEFFICIENCY (Cv)

The Flow Coefficiency (Cv) of a valve is the rate of gallons per minute of water at 60° F through a fully opened valve at a pressure drop of 1 PSI across the valve.
