Check Valve

Special Features

The Body to Bonnet joint is a male & female as per ASME 1501.3001 & 6001 and ring joint is used In higher classes valves.
Valves meet the requirements of fugitive emission levels Shell category-B as per MESCSPE 77 / 312
Low Friction Losses
Drip Tight Seating
Low Maintenance
No Hinge Pin or spring to Wear
Easy in-line serviceability

Category: Sap

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.

Free floating ball design provides seat wear compensation and longer life.
Provide fire safe design as per APO 607 / API 6FA / BS 6755-II with single point contact seat design.
Blow out proof and Anti blow out stem construction.
Micro-finished ball provides a positive seal.
Straight through flow path for minimum pressure drop.
Bi-directional flow.
90° (Quarter-turn) actuation.
Wide selection of seat materials.
Extended stem/extended bonnet design as per customer's specific pipe line usage.
Antistatic devices ensure electrical continuity between Body, ball & stem.
Triple stem seal with accurate stem.
Handle indicates flow direction.

SAP Gate Valves are heavy duty, outside screw & yoke type, bolted bonnet, rising stem with non rising hand wheel.
Straight through bore design assures streamlined, minimum turbulence, less erosion, lower pressure drop, & resistance to flow.
Anti- friction bearings are provided in higher sizes and classes.
Bi-directional shut-off.
Deep stuffing box.
The Seat rings are cylindrical bottom seated type having ample cross section for strength will provided with welded in and threaded Seat-rings will be supplied on request. Integral seat ring provides in SS valves.
Gate Valves are available in 150#, 300# & 600#.
Universal trim: 13Cr stem, wedge in CA 15 or 13Cr faced is also available.
Flexible wedge with low center stem wedge contact, in solid CA15 (13 % Cr) or hard faced with 13% Cr, SS 316, & Monel. Wedge is ground and lapped to a mirror finish and tightly guided to prevent dragging and seat damage, Non-rotating stem with precision Acme threads and burnished finish.
The two inclined seats allow for tight shut off even against high pressures. Renewable Seat Rings Welded or Threaded.
Gate Valves are of flexible wedge, outside screw and-yoke and bolted-bonnet construction. The valves confirm to API 600.

Standards: : Valve comply with BS 5155, API 609, MSS SP 67 and ISO 5752 valves designed to fit without gaskets between flanges drilled to ANSI 125, DIN. ND 10.16 BS 10 tables D E and F of BS 4505 PN 10/16 tables 6, 7 & 8 of IS: 6418 and tables. 11, 15 & 17 of IS: 6392
Note: : Face to face dimensions given in the installed condition (i.e. with liner compressed) Free length exceeds this dimension by 5 mm max. Depending on valve size. The minimum internal pipe diameter should exceed this dimension for correct installation.
Technical Data & Specifications : Size Range : 50 to 700 mm Pressure Rating : PN 10 / PN 16 / PN 20 Temp. Rating : Material will be selected according to service.
