NPTLOK 3 Way Manifold Valve
NPTLOK 3 way manifold valves consist of one high-pressure block valve, one low-pressure block valve, and one equalizing valve or the drain valve, which is placed between two block valves to equalize the pressure on both sides.
NPTLOK 3 way manifold valves include directly mounted and remote-mounted types. Directly mounted 3 way manifold valves have an integrated valve and have fewer leakage points. The remote-mounted 3 way manifold valve is mounted on the lines, not on the instruments.
NPTLOK 3 way manifold valve connections include Pipe to Pipe, Pipe to Flange, and Flange to Flange. Fewer connections can improve the layout and reduce leakage.
NPTLOK 3 way manifold valve construction is compact and rugged, which can withstand high pressure and high temperature. They are available in materials like stainless steel, carbon steel (Zinc Plated or Dichromated), Alloy, Monel, and other materials.

NPTLOK offers you a material test report (MTR) of 3 way manifold valve

NPTLOK 3 way manifold valve packing below stem thread

NPTLOK 3 way manifold valve will be 100% pressure test before delivery

NPTLOK offers laser printing on 3 way manifold valves.
Material Test Report Of 3 Way Manifold Valves
The raw material is very important for the quality of 3 way manifold valve, which is related to the pressure, anti-corrosion, and temperature. NPTLOK offers you the raw material test reports (MTR) of 3 way manifold valves for you to check the components. And MTR will be provided with every order for the pressure-containing components.


3 Way Manifold Valve Packing Below Stem Thread
NPTLOK 3 way manifold valve packing is below the stem thread, which separates the threads from the fluid flow. The fluid will not corrode the critical stem threads.
NPTLOK 3 way manifold valve stem threads are rolled, not cut the good quality stem, which lasts for longer service life.
100% Pressure Test Before Delivery
NPTLOK 3 way manifold valves will be 100% pressure tested before delivery to make sure you get good quality valves. And give you a pressure test report of 3 way manifold valves.


Laser Printing On 3 Way Manifold Valves
NPTLOK offers laser printing on 3 way manifold valves including the materials, pressure, temperature, and flow directions. The most important that we can print your own brand on 3 way manifold valves so that you can create your own brand in your market.

Functions Of 3 Way Manifold Valves
NPTLOK 3 way manifold valves allow transmitters to be isolated from the process loop. One of the block valves is high pressure for the pressure transmitter, and another block valve is low pressure. The drain or equalizing valve is inserted between two block valves to equalize the pressure on both sides.
NPTLOK 3 way manifold valves protect the instruments from too high or too low temperatures by increasing or decreasing the process temperatures.
NPTLOK 3 way manifold valves are used in a variety of industries including gas and oil, chemicals, instrumentations, petrochemicals, and so on.
Yes, we can offer you material test certificate of 3 way manifold valve.
Yes. 3 way manifold valve will be 100% tested before delivery.
If there are stocks in the warehouse, the sample of 3 way manifold valve will be sent to you. If there is no stock, the MOQ of production is 10 pcs.
3 Way manifold valve pressure range is from 6,000psi to 10,0000psi.
