FEATURES

• K-LOK polymer, elastomer, and fire-safe seats provide bi-directional, drop-tight closure in vacuum and throughout all pressure ranges, as well as at full rated differential pressure. A variety of materials allows optimum seat life in all applications.

• Blow-out proof shaft in accordance with API 609 provides increased operator safety.

• Integrally cast mounting pad provides direct mounting of many actuators.

• Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts reducing packing leaks.

• Extended neck allows for two inches of pipeline insulation.

• Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support resulting in reduced wear and longer life.

• Disc taper pins are tangentially positioned half in disc and half in shaft, placing them in compression rather than shear, which eliminates potential for failure.

• Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life.

PRINCIPLES OF OPERATION

Double offset disc/shaftK-LOK’s unique two-piece shaft and double-offset disc/shaft design allows for high cycling and creates a lower disc profile with increased capacity and a range of 33:1.In addition to increasing the flow area across the disc, this design minimizes wear points between seat and disc.The first offset is achieved by locating the shafts downstream of the center-line of the seat. This allows for a totally unobstructed 360° sealing surface.The second offset locates the shafts off-center of the vertical axis of the seat.The combination of these two offsets creates a camming effect as the disc swings into and out of the seat. The disc lifts quickly out of the seat in the first few degrees of travel and does not contact the seat again until it is nearly closed. There are no wear points between the seat and disc, while operating torques are reduced and seat life is extended.

Fire-safe packingK-LOK fire-safe packing is composed of three rings of preformed graphite between one ring of woven graphite rope at the top and bottom.This arrangement creates a superior, high temperature seal against the outer wall of the packing box and around the rotating stem.

Two-piece shaft vs. one-piece shaftK-LOK’s disc geometry maximizes flow capacity by increasing the available flow area through the valve. This increase in disc efficiency results in a higher valve Kv.

K-LOKtwo-piece shaft

FIRE-SAFE VALVE

The K-LOK fire safe version has been tested and certified to API 607 fire test.This design uses a stainless steel or alloy seat of convoluted shape that mates with an RTFE member. In the full-closed position, the K-LOK provides continuous two-plane contact between the disc and both metal and RTFE seats. The fire-safe seat utilizes wire windings to provide the circumferential stiffness necessary to maintain interference between disc and seat.

SEAT DESIGN

The K-LOK seat is a true interference seat design and does not rely on line pressure to assist in sealing. All seats seal drop-tight bi-directionally at low pressure as well as high pressure. This allows the K-LOK to provide a tight shutoff even in tough services that contain particulate.Polymer (PTFE, RTFE and UHMWPE) seats incorporate a stainless steel braided wire wrap, enclosed in a U-shape envelope to provide seating energy and memory. This wire wrap allows axial flexibility in both directions of flow. The wrap also allows radial flexibility when the disc is not fully closed, reducing seat/disc interference, seat wear and shaft torque. When the disc closes, it provides circumferential stiffness and assures the required disc/seat seals tight.Elastomer seats are molded around a stack of V-shaped steel rings that provide the same stability, support and flexure as the wire windings in polymer seats.Metal seats employ a stainless steel or alloy ring of convoluted shape, reinforced by stainless steel wire wraps. The thin, convoluted shape allows for expansion and contraction from thermal cycling. Long life is assured by flash coating the seat with chrome.

SEATING AND UN-SEATING TORQUE

Seating and un-seating torques are a function of the size of the valve and the shutoff pressure of the system.Specific torque ratings can be found in the seating/un-seating chart at the intersection of the ‘size’ row and the ‘shutoff pressure’ column.Torques listed are for PTFE and RTFE seated valves. For different seat materials, specific multipliers are to be used as stated.All torques listed are for normal service conditions (i.e. operating frequency is a minimum of once per month; disc corrosion is expected to be mild or minor, the media is a clean gas, liquid or steam, and is non-abrasive) and chemical effects upon the seat are minor.

NOTES1. Torques are applicable only to PTFE and RTFE

seats in noncorrosive or non-abrasive services such as water. For fire-safe and metal seats, select only the torque for the valve at 20 bar and multiply by 2.0.

2. For other seat materials, select the torque applicable for the maximum differential pressure and multiply by the following factor:

EPDM/NBR/Fluoroelastomer (FKM): x 1.4 UHMWPE (clean service): x 1.3For services that combine unfriendly conditions such as extreme temperatures and high solids, or corrosive with high temperatures, contact your sales representative.

NOTES1. Surrounding air temperature is assumed to

be 21°C. For every degree over 38°C of the surrounding air, deduct 2 degrees from the maximum temperature ranges shown under the Pipeline fluid temperature column. (Example: 52°C external temperature reduces maximum temperature values under the Pipeline fluid temperature column to 325, 410, 510, 600, etc.)

2. Valves may be insulated or uninsulated.3. Brackets may be open rectangular tubes or

the standard closed Keystone tubular shaft extensions.

4. All actuators have a maximum service temperature (outside atmosphere). These temperature limitations apply regardless of K-LOK extension lengths.

FLANGE GASKETS

The K-LOK high performance butterfly valve is designed to accommodate the use of standard, non-metallic gaskets for pipe flanges (such as compressed fiber, non-asbestos, flexible graphite or equivalent gasket materials), meeting the dimensional requirements of ASME B16.21-2011. Metallic wound gaskets may also be used, however, please note that any valve with a bolted on retainer requires the wound gaskets material to be manufactured to the following dimensions. Those dimensions not in bold are according to B16.20.
