PQ640F/H/Y pneumatic side-mounted eccentric semi-ball valve product overview

PQ640F/PQ640H/PQ640Y pneumatic side-mounted eccentric hemispherical valve and eccentric hemispherical valve are the same type of valve. The difference lies in its transmission form. The pneumatic side-mounted eccentric hemispherical valve uses a pneumatic device to drive the ball around the center line of the valve body. Rotate to achieve opening and closing. The valve has a large flow area and low flow resistance. This is because the valve core is located in the ball room after opening, and the fluid is directly connected; the operating torque is small, and the opening and closing can be completed by turning 90 degrees. It is easy to operate, tightly sealed, and double eccentric metal hard seal. Scaling does not affect the opening and closing, which is the most significant advantage of this product; it has a long service life, the sealing pair is wear-resistant, and there is a compensation amount, and the valve seat can be adjusted or replaced.
