PQ340F/H/Y-10C16P national standard WCB cast steel worm gear side mounted eccentric hemispherical valve

Product Overview

The PQ340F/H/Y-10C16P national standard WCB cast steel worm gear side mounted eccentric hemispherical valve use eccentric valve body, eccentric ball and valve seat. When the valve stem rotates, it is automatically centered in the common path. The tighter it is closed in the closing process, the better the sealing is completely achieved. The ball and the valve seat of the valve are completely separated, eliminating the wear of the sealing ring, and overcoming the problem that the traditional ball valve seat and the ball sealing surface are always worn. The non-metallic elastic material is embedded in the metal seat, and the metal surface of the valve seat is well protected. This product is especially suitable for steel industry, aluminum industry, fiber, small solid particles, pulp, coal ash, petroleum gas and other media.

Unique Advantages

• The structure adopts the eccentric wedge principle to achieve the purpose of locking, adjusting and closing through the transmission mechanism. The sealing pair is a metal-faced ring with hard-faced contact seal. When the double eccentric structure is opened, the valve core is located in the ball chamber, the flow section is large, and the valve is not washed. When the valve core is closed, the valve core is not washed. When the valve core is opened, the spherical surface of the valve core is gradually along the valve seat, effectively removing the scaling barriers, and achieving reliable sealing. It is especially effective for two-phase mixed-flow transport of easy-to-scale solids.
• The ball of the valve is made of bimetallic materials. Different alloys are overlayed on the base metal. The valve seat is also subject to corresponding overlaying and special treatment. The sealing surface is composed of anti-corrosion, wear-resistant, high-strength and other types to meet the needs of different occasions.
• Tightly sealed, no leakage of harmful gas.
• The valve core of the sealing pair is reserved with a compensation amount. When the valve is worn, it is rotated slightly when closed, so that it can be reliably sealed and the service life is extended. In addition, the user unscrews the compression nut, and the valve seat is still available after adjustment or replacement, so as to avoid the defect that the whole valve will be scrapped after the sealing failure of the valve.
• Ruiward valve source manufacturer has excellent CNC processing technology, and the design and processing dimensions are strictly in accordance with the industry front-end standards and 6S, CE, TS, ISO9001, ISO14000, ISO18000, API, GB standards.
