EH30, EH40, EH50, EH70, ER Valves

Clark Cooper Valve Option - General Service General Service (NEMA 4/4X)

Non-Hazardous Area In lieu of the standard “Explosion Proof” coil, you may opt for a coil classification that is designated as a “General Service” coil. This offers the option to reduce the cost of the overall valve price in situations where the standard “Explosion Proof” valve is not required.

Valves with an optional General Service Coil:
EH30, EH40, EH50

Clark Cooper Valve Option - Din Connector Din Connector (NEMA 4/4X)

The Din Connector (43650A/ISO 4400) allows a quick electrical connection to the coil utilizing a “3-prong” power connection to the coil. Gives added flexibility in providing another electrical connection option to your application and environment. Coil is rated for General Service.

Valves with an optional Din Connector:
EH30, EH40, EH50

Clark Cooper Valve Option - Explosion Proof 1/4" Tab (Spade)

A coil power connection option, that allows you to connect the valve’s coil to your specific power connection type. Coil is rated for General Service.

Valves with an optional 1/4" Tab (spade):
EH30, EH40, EH50

Clark Cooper Valve Option - NEMA 4X NEMA 4X

A coating is applied to the external surfaces of the coil to improve its corrosion protection.

Valves with NEMA 4X:
EH70 (optional), ER Valves (standard)

Clark Cooper Valve Option - Screw Terminal Screw Terminal

A coil power connection option, that allows you to connect the valve’s coil to your specific power connection type. Coil is rated for General Service.

Valves with an optional Screw Terminal:
EH30, EH40, EH50

Various Connections

Clark Cooper Valve Option - SAE Port SAE Port

Multiple sized connections (per SAE J1926) that utilize an O-ring for sealing to the valve inlet and outlet. Gives added flexibility in providing another valve connection option in lieu of NPT, Flanged, etc.

Valves with an optional SAE Port:
EH30, EH40, EH50, EH70, ER Valves (up to 1")

Clark Cooper Valve Option - Tube Connector Tube Connector

This connection attaches to directly to high pressure tubing. It allows the customer more connection flexibility by utilizing standard Swagelok® connections.

Valves with an optional Tube Connector:
EH30, EH40, EH50, EH70, ER Valves (up to 2")

Valve Options

Clark Cooper Valve Option - Integrated Check Valve Integrated Check Valve

Option to provide the EH50 valve with protection against back pressure. Gives customer a “ONE” piece integrated check valve built into their high pressure solenoid valve. No need for separate check valve purchase.

Valves with optional Integrated Check Valve:
EH50

Clark Cooper Valve Option - 316 Stainless Steel Valve Body 316 Stainless Steel Valve Body

Option of making the body of the valve with 316SS instead of the standard Anodized Aluminum valve body that comes on the EH50 Series valve. Option provides customer flexibility in choice of construction materials where service requirements and material compatibility may call for a change from the standard design.

Valves with optional Stainless Steel Body:
