Technical Descriptions:
Construction
Gate valves utilized in steam systems have flexible gates. The reason behind utilizing a flexible gate would be to prevent binding from the gate inside the valve once the valve is incorporated in the closed position. When steam line is heated, they'll expand, causing some distortion of valve physiques. If your solid gate fits snugly between your seat of the valve inside a cold steam system, once the product is heated and pipes elongate, the seats will compress from the gate, wedging the gate together and clamping the valve shut. This issue is overcome by utilization of an adaptable gate (two circular plates mounted on one another having a flexible hub in the centre). This design enables the gate to flex because the valve seat compresses it, therefore stopping clamping.
