Ordering information

References are formed by three parts:

 Valve Code  -Look for it in the order codes chart on the previous page.
 Option/s  -If required, add the code/s from the options section on the previous page (in alphabetical order).
 Material  -Look for the code on the materials chart.

An example of valve with two options:
The valve CP-01 1/2"BSP Duplex with grafoil packing and bleed screw in outlet:
 0016   GP   AD  The reference required to place the order is: 0016GPAD




100% tested in accordance to API STANDARD 598, each valve is tested to check the leakage in the seats and packing. Upon request, the corresponding materials and test certificates can be delivered with the valve.


All TECVAL valves are supplied packed in individual polyethilene, airtight bags. End screw connections are protected with polyethilene caps. Everything is 100% recyclable.


Adjustment of the packing may be necessary during the working life of the valve. The operation consists of turning the nut (3) clockwise. Valves with long no-working period may have a harder initial operating torque.
