4 Operational principle of the Bostar KHI sealing system Due to the elastic system in the b valve, leak-tightness is guaranteed at high as well as at low pressures. These two independently working sealing elements are preloaded during assembly. Furthermore they are driven against the b by the differential pressure of the media. As it is a trunnion mounted b valve, the pressure is not transmitted onto the seat rings. The valve can be used bidirectiony. Expansion caused by heat is compensated by the elasticity of the sealing elements. This elasticity provides continuously two main-sealing areas in the bore up to a certain pressure rate. With the fluid pressing onto the differential surfaces of the sealing element the seat ring is squeezed to the b surface. As soons as pressure from the clearance volume is admitted to the b and exeeds the nominal pressure, the b pushes against the sealing ring on the outlet and keeps it tight to the atmosphere as well. Operational principle of KLINGER Bostar sealing system Hexagon headed bolt Locking disc Supporting ring Cover disc B Sealing element KFC Supporting disc Body Circlip U-section sleeve O-ring (AF) Standard internal sealing system Cushion joint O-ring (AF) Bearing bush O-ring (AF) The usage of other materials is possible Bearing bush Cushion joint Retaining screw O-ring (AF) Standard sealing system of the operating stem 4

Two resil - ient sealing elements made of acid resistant steel with sealing ring and a sealing at the periphery of the supporting cushions joint, together with the b, form a sealing system that works in both flow directions. A supporting ring protects the resilient sealing element from overstress. The sealing unit is held by a circlip. Because of the special sealing system the clearance volume of the b valve can be drained, ventilated or relieved from pressure through a bleeding connection. This ows to check if both sealing rings are tight, after the pressure has been relieved (Block & Bleed). It additiony ows repairs in a depressurised pipe section between two b valves. The Bostar b valve is acknowledged by TÜV as double acting shut-off valve in compliance to TRD and UVV (technical guidelines for steam boilers).

7 Automation of valves With automation continuously rising, different types of actuators are being applied for which extreme reliability is indispensable. Different kinds of demands can easily be met with the help of actuators. Modular mounting and a wide range of accessory units which can be updated, make it possible to satisfy individual customer requests and adaptions to specific applications. Two types of automatic actuators are available: Directly operated the actuator is directly connected with the operating stem via coupling. Indirectly operated the actuator acts via intermediate gearing. Recommendation If the manual force for operating is higher than 5 Nm we advise you to use a mechanical gear. Suitable actuators Due to the flange connection acc. to ISO 5 lots of different gears and actuators from various manufacturers can be easily attached to Klinger Bostar KHI b valves. Torques for actuator dimensioning Standard design, KFC seat rings Operating pressure 5 bar: Standard design, KFC seat rings Operating pressure 4 bar: Standard design, metal seat Operating pressure 6 bar DN Standard design, metal seat Operating pressure 5 bar: DN Please note that: Genery the above specified values accord to the maximum breakaway (static) torques. At difficult operating conditions (pressure, temperature, media) and if the valve is operated less than 4-times a year we recommend to contact our technical department. In such cases the corresponding torque value (Mt) has to be multiplied by a safety factor to choose the best suitable actuator.

The two independent sealing elements, one on each side of the b with their preloaded springforce, keep leaktight at any time bidirectional and in operating conditions even with vacuum! KLINGER Bostar makes up for two valves of any kind! This means both cost and space savings. KLINGER Bostar: Test acc. to EN 488 at FFI The district heating-research institute in Hannover (FFI) tested the KLINGER Bostar b valves acc. to EN 488. During this test the valves are exposed to different kinds of axial tensions and pressure loads at a temperature of 4. C. The leak tighness of body, shaft and seat is tested and the operating torques are determined.

Countries which use the inch as measuring unit the c V -value replaces the k V -value. This value indicates how many US gal. of water, at the temperature of 6 F and a loss of pressure of psi, pass the valve every minute. c V =,558 KV k V =,865 CV Variation : b valve with reduced bore Dimension: 8/7 cast version -value:,5 k V -value: 5 8 m /h Variation : b valve reduced with welding cones Dimension: DN 8/7 -value,89 k V -value: m /h Observe the relation: kv kv full port redued port full port redued port I n t h e i n t e r e s t o f t e c h n i c a l p r o g r e s s, d e s i g n a n d d i m e n s i o n s a r e s u b j e c t t o m o d i f i c a t i o n 9

10 The pressure/temperature-diagram helps you to choose the optimal b valve Pressure-temperature limits The PT-diagram clearly shows what impact the material of body, sealing, bearings and screws has on the application range of the b valve. Place your operating point in the diagram field to see if the safety margins meet your requirements. A decreasing operating pressure in the nominal pressure range increases the field of applications in the temperure range. If you choose your b valve in this way you optimize the economy of the valve.

Among other things we offer special designs and accessories as follows: Regulation blind (equal percentage, linear, u.a.)

To avoid injury it is recommended to connect the drain cock to a drain pipe. Applied for superheated water it has to be considered that, depending on the valve size, the draining procedure lasts for some time. With the drain cock it is possible to check the block & bleed function, i..e. the b valve can be tested whether it is leaktight. 5

28 Economicy optimised and future-proofed because of modular design Due to the trunnion mounted b, single sided loads, which are acting on sealing elements, are avoided. This guarantees high leak tightness and increases the service life. Worn sealing elements can be substituted on the spot, economicy, without a specialist or KLINGER technician. Regarding stock keeping it means that you only have to store sealing elements or sealing kits and not complete b valves. Bostar b valves which are already on stock can be fitted supplimentary with metal sealing elements. This ensures consistency of design throughout the plant. Special surface coatings of the b Hard-chrome Chemical nickel Wolframcarbid Special surface coatings should be choosed acc. to requirements of the operating media. 8
