| All Design for Most Critical Steam Working Conditions |
 | Forged Full Machined Body Design To suit the high pressure and temperature conditions, the LV963/663Y PRV uses forged material for body construction, compare with casting body, forged full body has better mechanical property and strength endurance, able to handle thermal fatigue critical for reliable service, ensure the safe, trouble-free performance during the continuous operation. | |
 | Pressure Seal Construction Pressure seal construction is adopted for body-bonnet joints, seals performance improves as the internal pressure in the valve increases, maintains tightness regardless of thermal transients. | Pressure reducing valve
|
 | Pilot Plug Design Pilot plug design, means in the closed position, the main plug within the valve is unbalanced with full steam pressure acting on top. Combined with the actuator thrust this creates an extremely high seat contact and ensures a very tight shut off. | |
 | Very Tight shut-off The Seat surface is treated with hard stellite faced, the import | |
 | Radiator Structure Design To suit the high pressure and temperature conditions, the LV963/663Y PRV uses forged material for body construction, compare with casting body, forged full body has better mechanical property and strength endurance, able to handle thermal fatigue critical for reliable service, ensure the safe, trouble-free performance during the continuous operation. | |
 | Multihole Cage Design The Multihole cage guided trim is capable of managing large pressure drops and reduces the negative effects of erosion, cavitation, and noise. With the different working condition, the cage can be custom-designed with flow characteristic including of equal-percentage and linear to obtain the highest accuracy of desired steam pressure | |
We carry out the strictly packing procedure to ensure the safety and trouble free delivery. |
