Feature: kpf balance valve is a special feature of the valve, which has a good traffic flow characteristics can be reasonably allocated to achieve quantitative flow, can effectively solve the heating (air conditioning) systems at room temperature in the presence of hot and cold uneven problems. As the valve opening degree of instruction is provided, and the opening of the locking device for flow measurement manometry small valve, so long as each branch and customer specifications entrance fitted with appropriate balancing valve, and with a special one-time smart meters after commissioning the lock, you can control the total amount of water systems within reasonable limits, to overcome the "big flow, small temperature difference" unreasonable phenomenon. The product is ideal for the heating system, the maximum medium temperature of 100 .

FeatureUJ41H plunger valve is covered by the valve body, valve stem, plunger, guide, seal rings, hand wheels and other parts. When the hand wheel rotation, driven by the plunger on the stem in the guide sleeve, the lower reciprocating plunger end portion of the oblique cone cone complete with seat valve opening and closing function. Plunger valve seal between the piston and ring interference fit by adjusting the flange bolt preload, compression of the sealing ring lateral force and the body bore cylindrical surface of the plunger seal produced, thus ensuring the valve seal, to prevent internal leakage. Since the sealing ring resiliency strong, high abrasion resistance, non-toxic new sealing materials used, so the seal is reliable and durable. Thereby increasing the life of the plunger valve. Combination plunger valve plunger valve leak a little and shut-off valves open and close and fast become a novel structure, extensive use of new products.

Feature:Heat efficiency lose: due to the drop of throttle steam temperature caused by spray valve leakage, heat efficiency will be affected and extra heat will be needed for the boiler to keep the throttle steam temperature at the set point.Temperature control: poor control of the steam temperature may also affect the high pressure steam pipe and turbine.When the pressure is higher than 12.4Mpa(1800psi), each temperature change of 19-2230-40 would lead to 1% heat efficiency change.Higher maintenance cost: frequent replacement and maintenance will be needed due to the plug erosion damage.
