Steam Control Valve of Self-Actuated Thermostatic Temperature
Style, PN 40 Bar
PRODUCT INTRODUCTION
1. Description
ZZWP self-operated temperature control valve is composed of
temperature sensor and control valve. It is a kind of energy-saving
product which can automatically adjust the temperature of
controlled medium without external energy. The product is suitable
for automatic temperature control in various heat exchangers with
various gases, steam, hot water, oil and so on. Wide range, easy to
adjust, continuous temperature setting, over-temperature
protection, temperature setting convenience and other advantages.
Widely used in urban heating, heating systems and power, oil,
metallurgy, pharmaceutical, boilers and other industrial sectors.
2. Feature of Control Valve
The self-operated temperature control valve does not need external
energy, such as electricity or compressed air, safe and reliable.
Temperature sensitive liquid expansion uniform, proportional
regulation control, high control precision, stable work, effective
energy saving, balanced valve body design, so that the valve can
work under greater pressure difference, linear or equal 100
specific flow characteristics, temperature setting operation simple
and convenient, small size, light weight, installation It is
convenient.
