When the credit status reflecting a corporate credit situation is quantified as the specific value of credit point, plus the value of credit point accumulated in the course of longtime online trading, it is turned out to be the credit point for this company.
high-pressure valve has 2 versions. One is 2-Way Version, its operations could be described as below: When pressure is applied to the PILOT port, the main ports (IN and OUT) are opened to allow flow through the valve. When the pilot pressure is released, a spring closes the main ports.
Another one is 2-Way Vented Version, its operations could be describes as below: When Pilot Pressure is applied to the PILOT port, IN Port is open to the OUT Port; the VENT Port is closed. When pilot pressure is removed, the IN Port closes while the VENT Port opens to the OUT Port, relieving pressure within the valve and down stream piping. When used on a fuel gas system, the fuel intake manifold is vented causing quick shutdown of the engine.
