The KLINGER Ballostar KH(SV)I in the district heating industry
KHI ball valves will keep up with stricter requirements and are assured to already meet future standards with regard to tensile, compressive and bending stress. The KLINGER Ballostar® KHSVI VVS ball valves, certified in accordance with EN 488:2019, are ideally suited for underground installations thanks to their robust, pre-insulated design.
The KH(SV)I convinces with many impressive advantages:
1. Robust body
Plant operators are concerned of high tension/compression forces under the effect of heat. To ensure that the valves remain operable over time, they are tested acc. EN488, Advantages of casted material: tension free and no complex weldings.
2. Trunnion mounted ball
In order to avoid any deformation of the sealing elements and a risk of blocking of the ball, the sealing and guiding functions must be disassociated and trunnion mounted ball valves must be installed.
3. Full bore
There is no obstacle or reduced flow of the passage of the fluid. The flow is laminar. The pressure losses are minimal and the energy cost for handling the fluid is reduced. Also smaller pumps can be used.
4. Reliable sealing system (leakage rate A)
The pre-stressed diaphragm springs ensure contact of seat with the ball. Seat is fully enclosed and fixed in the housing. Impurities can circulate easily behind the diaphragm springs - there is no retention zone.
5. Double block & bleed
Safest solution for maintenance and smallest installation space. After pressure relief --> the test valve allows to check the seat tightness.
6. Easy handling
The mounting direction and position is irrelevant (bi-directional sealing). Extensions, gear boxes or actuators can be fitted easily via ISO top connection.
7. Maintenance free
KLINGER Ballostar ball valve model KH(SV)I is basically maintenance free --> estimated lifetime 25 to 30 years based on experience. If necessary, the stem O-rings could be changed inline.
