Tyco pumping system recommended valves include
Bleed valve quick-closing butterfly valve (heater protection valve) - Model QSB/BHP
Exhaust valve - Model PC20
Pump air and two sections of air gate valve
Parallel plate gate valve Model PGD
Flexible wedge gate valve Model GAPD


The teke QSB/BHP series express valve is used in the gas waste heat power generation system and the extraction steam heating steam turbine system. The valve is the guarantee of the system security and is widely used.
Quick closing of the butterfly valve, small circulation resistance, and sealing, etc., can replace the electric globe valve and check valve in the original system design.

Design features

1. The quick closing time can reach 0.5 seconds, and the emergency shutdown is safe and reliable.
2. 3 eccentric metal, sealing structure and light and flexible, sealing zero leakage.
3. The normal temperature medium can be used double eccentric soft sealing structure, low cost and reliable sealing.
4. The valve end buffer is effective to avoid valve inertia impact.
5. The quick closing can be realized with the spring, the liquid can be realized by the accumulator, and the two forms of the same work are equally safe and reliable.

Product range

Size: 2-128 ((~ DN3200)"
Stress level: 150 ~ 900LB (PN16 ~ PN150)
Main material: carbon steel, stainless steel
Internal components: carbon steel, stainless steel, composite materials

use

The quick-closing butterfly valve is mainly used in the thermal power plant shunt unit and the gas waste heat generator set to be used as an emergency cut-off valve for the safety of the system.

Tyco PC20 series smoke reversed flow of qi check valve for high pressure cylinder exhaust pipe of the steam turbine power Station Road or other requirements rapidly closing industrial pipeline system, the air pressure (0.5 ~ 0.7 Mpa) or under the influence of the return spring quickly shut down (closing time of 0.5 s or less), steam turbine and other devices to prevent the backflow medium damage.

Design features

Minimum pressure drop design is easy to maintain.
The PC20 series check valve can be completely removed from the pipeline to realize the replacement of the internal components of the valve, which greatly reduces the cost of maintenance and maintenance.
The PC20 series check valve adopts monel alloy bushing, which can effectively prevent the use of low corrosion resistant materials.
If used in a vacuum, the PC20 series check valve can increase the water seal.

The tyco PGD series parallel plate gate valve
Unique design offers lower pressure drop than wedge-shaped gate valves, while in the field of steam and water applications
For maximum reduced flow turbulence, reliable cut-off capability and longer service life
