1.6 Description of the Model 700 Control Valves

1.6.1 General features of the control valve

The Daniel™ Model 700 Control Valve operates on a balanced piston principle, spring

biased (loaded) to the closed position.

The valve can be configured as a check valve to prevent reverse flow. It is possible, in some

applications, to reverse flow through the pilot control loop, but this can be eliminated by

installing a check valve in the X-port.

User manual Introduction

P/N 3-9008-553 November 2020

User manual 9

The Daniel Model 700 Control Valves have the following characteristics:

•Modular construction: All internal parts including seat ring can be removed with the

cylinder assembly without disturbing line connections.

•No diaphragms or stuffing boxes

•45° body design assures high capacity

•Positive shut-off

•Uniform speed-of-response

•Linear control

•O-ring plus metal-to-metal seat

•Pilots and other optional accessories enable the valve to perform a variety of control

functions such as back pressure control, regulating rate-of-flow, pressure relief, surge

control, etc.

1.6.2 Control valve applications

This is the starting point for unlimited control applications. The basic valve needs to

incorporate a pilot control loop, which is mandatory for it to function, see Daniel Liquid

Control Valves Technical Guide (P/N DAN-LIQ-TG-44) for specific applications.

1.6.3 Operation overview of the control valve

The basic valve operates on a balanced piston principle, spring biased (loaded). Refer to

Figure 1-1. The term balanced piston means that the exposed area on the spring side (P3)

of the piston and the bottom side (P1) are equal in area. The spring is the differential force

that closes the piston when (P1) and (P3) pressures are equal.

To open the valve, the pressure against the bottom of the piston (P1) must exceed the

pressure on the spring side of the piston (P3) plus spring force.

Closed position

Figure 1-1 illustrates the closed valve. Y-port (P3) to Z-port (P2) is closed. X-port (P1) and

Y-port (P3) pressures are balanced. The differential force created by the main valve spring,

closes the piston and keeps it seated.

Therefore, total pressure equals 40 psi @ (P1) and 45 psi @ (P3) or (P3 minus P1) - 5 psid.

The needle valve/strainer controls the speed of the closure by controlling the flow through

the X-port.
