Detailed Introduction

Structure

The valve is composed of a valve body welded and carbon reinforced Teflon gasket,in frequent operation,impurities and chemical substances under the condition of long service life.Grinding fine stainless steel ball can guarantee for many years to open and close,reliable operation.

Adopt floating ball structure,inclined plane elastic washer to ensure that the sealing ring is pressed on the ball,even in the case of unstable pressure,the valve can ensure tight.

The valve stem leakage structure using two"O"-shaped ring,so that the valve stem rotation and sealing.

Characteristic

Do not need to maintain,adjust and lubrication,easy to install in the ovw operating cost of long-term reliable operation.

Valve stem can be lengthened,easy to heat insulation.

The operating handel can be removed and the reverse is installed.

The body does not contain heavy and unreliable castings.

Install regulator,very simple.
