Product Overview

Grease seal high temperature control valve of grease injection type produced by TangoValve Group can be widely used to control various kinds offuids with different pressures and temperatures. The valve body is com-pact and the fow channel is S-streamlined, with the characteristics of small pressure drop loss and large flux, wide adjus-table range andhigh accuracy of fow characteristics. The balanced plug structure, adopted for the valve, has the advantages of good valve stability, low vib-ration, low noise and low temperature sensitivity. lt is widely used in occasions of large flow, high temperature, and leakage requirements not strict.

Product Features

Grease-Seal-High-Temperature-Control-Valve-Structure

The plug has rich Cv value, and the sealing performance of the valve seat is in line with the international industry standard of the regulating valve. The regulating valve is equipped with pneumatic or electric actuator, with compact structure and large output force, which is more suitable for the control use in the high temperature situation requiring high reliability and closing performance. The service life and sealing performance of the valve stem packing can be signifcantly enhanced by adding the structure of sealing grease and double-layer sealing when it is used in steam and high temperature conditions.

 

Design features

1. With top guide structure

2.Large fow coefhcient and wide adjustable range

3.Double sealing structure, more reliable sealing

4.With heat sink, strong heat dissipation function

5.With grease injection tank, longer packing life

6. Mainly used in high temperature steam, hot oil and other occasions
