Portable breathing valve test bench PTP-4
A new type of breathing valve test bench with independent intellectual property rights developed according to the actual needs of users;
Use vacuum negative pressure to test the suction set pressure of the breathing valve and use external positive pressure to test the exhalation set pressure of the breathing valve. It is essential equipment for the factory inspection and safety inspection during the use of the breathing valve;
It is widely used in special inspection, nuclear power, petrochemical, valve manufacturers and other industries.

1. The positive and negative pressure tests are integrated on the same equipment, which makes the switching between positive and negative pressure tests convenient;
2. Equipped with high-precision digital pressure gauge and mechanical pressure gauge to display the test pressure;
3. Equipped with gas tank and regulator to ensure accurate test results;
4. Safe and reliable with manual clamping and four claws;
5. Low maintenance and repair parts cost, long service life.
6. Flow test function and pressure flow test software can be added.

1. Test medium: dry and clean compressed air or nitrogen, inlet pressure<6 bar;
2. Test pressure: exhalation set pressure 0.8 KPa~30KPa, suction set pressure -0.28KPa~-0.5KPa;
3. Test range: DN50-250mm;
4. Power supply:
Air source: dry and clean compressed air or nitrogen, with pressure less than 6 bar. The user is responsible for reducing the pressure when supplying air with nitrogen cylinders.
5. Dimensions and weight:
Control bench: about 386L*417W*295H (mm), 25Kg;
Manual clamping bench (including vacuum tank installed at the bottom): about 680L*450W*630H (mm), 40Kg;
Accessory box: about 470L*320W*265H (mm).
