Instrumentation Valve


Mcneil Instruments Inc offers a variety of 2 Valve manifolds instrument. The 2 Valve manifolds are designed for static pressure and liquid level applications. These manifolds are available in traditional and compact body designs. Manifold connections include female tube fittings, pipe ends (NPT and ISO 228/1), and flanges (MSS SP-99) in 1/2 and 3/4 in. and 12 mm sizes.

We are the trusted name in the industry when it comes to the manufacture and supply of valves, fittings and industrial couplings with adapters. We have served a wide variety of industrial sectors, and supply products which conform to industry standard requirements and ensure safety and system efficiency with their precision design.

2 Way, 3 Way, 4 Way, and 5 Way Manifold Valve

Mcneil Instruments Inc. is one the best manufacturer, Supplier, and Exporter of 2 Way, 3 Way, 4 Way, and 5 Way Manifold valves In India

Types of Manifold Valves

Manifold valves are divided into the following categories based on the number of valves and the design configuration:

  • 2-way Manifold valves,
  • 3-way Manifold valves,
  • 4-way Manifold valves,
  • 5-way Manifold valves.

2 Way Manifold Valve

A combination of an isolation valve and a calibration/vent (bleed) valve makes up a 2-way manifold valve or 2-valve manifold, which is constructed as a single block. They have screwed intake and outlet ports that are either male or female. The bleed valve is identified by a red handle, whereas the block valve is identified by a blue handle. They are typically made of conventional PTFE valve packing and 316 stainless steel. 2-way valves can be configured in an in-line, L-shaped, or Y-shaped manner.

3 Way Manifold Valve

One equalizing valve and two block valves make up a 3-valve manifold, often known as a 3-way valve manifold. Examples of 3-way manifold valves in use are often differential pressure transmitters. The equalization valve often has a green handle, whereas the block valves are distinguished by blue handles. The block valves are open and the equalizing valve is closed when everything is operating normally. In a 3-way manifold valve, the block valves provide instrument isolation. The equalizing valve ensures that the pressures on both sides of the pressure instrument’s high and low process connections are equal.

Due to the absence of a test connection, the 3-valve manifold is rarely used in the oil and gas sector. Unblocked test connections are included with some 3-valve manifolds.

4 Way Manifold Valve

4 way For air-powered machines, manifold valves are a small flow control component that is used to pressurize air and distribute it to various ports, where it is used to activate various actuators for controlled and effective operation. It is made with the aid of cutting-edge technologies, which produce a high-class finish and zero production faults. The high tensile strength of the steel used in production enables it to withstand intense pressure and difficult industrial conditions. Purchase this superior 4-way Manifold Valve from us at a fair and affordable price.

5 Way Manifold Valve

Two block valves, one equalizing valve, and two vent or test valves make up a five-way manifold valve or five-valve manifold. The equalization valve has a green handle, the bleed valves have a red handle, and the block valves on the high and low pressure sides have blue handles. The block valves stay open while the bleed and equalizing valves are kept closed during normal operation. A differential pressure transmitter is a common use for a 5-way manifold valve.

The equalizing valve is opened while the block valve is closed to check the transmitter’s zero. Once the pressure has been equalized, the test valve is linked to a pressure generator to calibrate the transmitter for 3 or 5-point calibration.
