4047 Pressure Valve

Product catalog summary

Key Features and Benefits:

The 3-way valve features a balanced force design, allowing pressure application at any port.
It includes easily replaceable Buna N (Nitrile) 'tadpole' seals and provides bubble-tight seals with a center dead spot to prevent port overlap.
The valve comes with a Gulfproof finish as standard.

Typical Applications:

Used for sensing low pressure or vacuum in water, air, natural gas, oil, and more.
It can detect overload on gas engines and sense vacuum intake air manifold.

Overview:

The AMOT Model 4047 is a high capacity, low pressure valve that can function as a 2-way or 3-way valve. It operates over a range from 0.007 bar (0.1 psi) to 0.77 bar (11.2 psi). It is suitable for sensing low pressure in gases, liquids, and for liquid level control. The valve can also sense vacuum pressure when connected to the vacuum port.

Specifications:

Valve body and diaphragm housing are made of Gulfproofed anodized aluminum.
The valve spool is constructed from glass-reinforced Ryton.
Standard seals and diaphragm are made of Buna N (Nitrile).
Maximum operating pressures at ports are 8.6 bar (125 psi), with a maximum continuous control pressure at the diaphragm of 1.4 bar (20 psi).
Proof pressure for the diaphragm is 2.1 bar (30 psi), and the maximum temperature is 66°C (150°F).
The valve has a free flow area with a Kv of 1.0 and a Cv of 1.2, and it weighs 2.3 kg (5 lbs).

Operation:

For 2-way operation, the valve opens on rising or falling pressure by plugging specific ports.
For 3-way operation, no ports are plugged, and the valve opens and closes ports based on pressure changes, with a 'dead spot' preventing simultaneous opening of Ports 1 and 3.

Ordering Information:

Customers can select specifications based on pressure range, reset type, seal material, and any special requirements. Example order code: 4047B A B C D - EE.

Maintenance:

Model 4047 requires minimal maintenance, with annual inspections recommended. Monthly checks are advised to ensure proper functioning by simulating unsafe conditions.

Service Kits:

Service kits are available with Buna N or Viton materials, including O-rings, diaphragms, and seal rings.

Contact Information:

AMOT provides contact details for their offices in Europe, the Middle East, Africa, the Americas, and the Asia Pacific regions.

Catalog excerpts

Low Pressure Valve Model 4047 Overview AMOT Model 4047 is used as a 2-way or 3-way high capacity, low pressure valve for settings from 0.007 bar (0.1) psi falling to 0.77 bar (11.2 psi) rising over several ranges. Applications include sensing low pressure low pressure gas, water, fuel, oil, or for liquid level sensing and control. By piping to the vacuum port, the valve can be used to sense vacuum pressure from 0.007 bar (0.1) psi falling. The 4047 can detect overload on gas engines by sensing the vacuum pressure in the intake manifold. Typical applications • Sense low pressure or vacuum of water, air, natural gas, oil and more Detection of overload on gas engines Sensing of vacuum intake air manifold 3-way valve has balanced force design Pressure can be applied at any port Buna N (Nitrile) “tadpole” seals are easily replaced Bubble-tight seals with center dead spot (no port overlap) Gulfproof finish standard

Low Pressure Valve - Model 4047 Valve to open on rising pressure Port 1 must be plugged. Rising pressure will open Port 2 to Port 3 above the trip point. Valve to open on falling pressure Port 3 must be plugged. Falling pressure will open Port 2 to Port 1 below the set trip point. Valve operation for 3-way action is identical with that for 2-way except that there will be no plugged diaphragm housing Valve spool diaphragm Buna N (Nitrile) Maximum operating ports. On valves set to trip on rising pressure, Port 1 will open to Port 2 until just below the trip point. Port 3 will open to Port 2 at...

Low Pressure Valve - Model 4047 Maintenance Properly applied and installed, Model 4047 requires minimal maintenance. Unless leakage or other problems are noticed sooner, an inspection of the units at yearly intervals is adequate to detect and make provision for normal wear and preventative maintenance. It is recommended that the valve be checked monthly if possible for proper functioning by simulating an unsafe condition. Service kits STAMP "P" Seal ring Seal ring
