DE STA CO's Needle Valves are multiple-turn flow restrictor v alves which provide finely adjustable flow control for components or circuits requiring reduced flow rates. They are also used in some non-critical sequencing applications where restriction is part of a circuit will tend to cause the actuators in the remainder of the circuit to operate first.

Needle valve NO. 15068DE has a reverse free-flow check valve built in to allow unrestricted flow in one direction.

Needle valve NO. 253605DE restricts flow in both directions.

Features:

• Corrosion resistant construction
• 5,000 psi maximum

For dependable performance of cylinders, clamps, valves, and pumps, DE STA CO's high grade Hydraulic Fluids contain anti-rust, anti-foam, and anti-sludge additives. They provide maximum film protection lubricity, maximum heat transfer, and a wide operating temperature range.

DE STA CO's "environmentally friendly" hydraulic fluid is biodegradable, non toxic formulation which can withstand severe operating conditions and provide excellent anti-wear properties.

The "Flame-Out" fire resistant fluid has been approved by United States Mine Safety Health Administration under Referral Register Title 30, Part 35. All fire resistant fluids will burn if heat source is extreme, eg.: hot slabs, molten steel, etc. They will not, however, propagate the flame and are self extinguishing in the absence of an ignition source.

They use of the fires resistant fluid does not require changing the seals in any DE STA CO equipment as it would when using other types of fire resistant fluids. The standard fluid need only be drained from the complete system and replaced with fire resistant hydraulic fluid.
