DHH44X Tilting Type Check Valve

PRODUCTION：

Tilting type check valve is a kind of multifunctional butterfly type check valve; low pressure damage and completely eliminating water hammer. It is usually installed in the outlet of the pump, which takes effect in checking, closely shut off and opening.

FEATURES:
1. After opening, the shaft and disc is in the upper side position; the vacant main channel is convenient for fluid passing. Disc adopts arc streamlined design (Turtleback Shape), for reducing head loss. The valve adopts small -size hydraulic pressure station, picking up disc, flow resistance will be up to 0.**2Mpa.
2. The sealing face adopts high-quality S.S. Welding technology. After sealing face processing with a better fineness and anti-corrosion property; and also with a long service life span.
3. The seat adopts conical design with sealing property, for ensuring a reliable sealing.

4. With a self-lubricating composite bearing; high abrasive resistance;

little friction coefficient; bearing (disc) rotating flexibly.
